Title: “Microwave Sensing and Inverse Scattering for Environmental and Biomedical Imaging Applications”
This presentation will provide an overview of ongoing research in our group in the general area of applied electromagnetics, with multipronged theoretical, computational, and experimental approaches to solving realistic sensing problems in complex media. These problems include (1) radar remote sensing of the Earth environment, in particular for characterization and monitoring of subsurface and water resources, and (2) noninvasive and non-ionizing microwave medical imaging, therapy, and monitoring systems.
Radar remote sensing has long been recognized as a key component of an effective environmental observing strategy, due to the strong relationships of radar measurements with geometric and compositional properties of the Earth’s landscape. Recognizing the sensitivity of radar measurements to the variables defining the landscape, especially water content, many radar instruments have been flown by space agencies around the globe on airborne and spaceborne platforms for synoptic observations. Here, we outline some of the critical problems in environmental remote sensing today and discuss how our research addresses a number of the shortcomings by developing new sensor technologies, electromagnetic scattering and inverse scattering models, and physics-based statistical signal processing algorithms. The focus will be on remote sensing of water resources with low-frequency radars and employing computational scattering and inverse scattering methods. The emerging research for mapping profiles of soil water content (‘soil moisture’), variations in permafrost properties in the arctic and boreal regions, and
Electromagnetic waves in the microwave regime have also been used for a variety of medical applications in the past several decades. Microwave imaging was perhaps the first such application. More recently, non-contact hyperthermia (microwave) and invasive probe-based ablation (radio frequency (RF) and microwave) methods have seen clinical use for thermal therapeutic purposes. The attraction of such methods is the highly efficient and deep heat deposition property of microwaves in biological tissue, especially those with high water content. A main challenge with such systems, however, is monitoring the temporal and spatial progress of heat deposition for proper treatment. This talk will include an overview of our recent work on the development of microwave imaging, thermal therapy, and thermal monitoring systems, with emphasis on the latter. A summary of analyses and results will be included to show successful retrieval of temperature fields with a precision of better than 1 o C and spatial resolution of about 2-3 cm at a refresh rate of about 1 frame per second, which makes this method realistically useful in a clinical setting.

Title: “5G Antennas and Its Measurements”
Wireless data transmission rate in 5G system will be further increased in near future by carrier aggregation, massive MIMO and pico cell system. Frequency band width is extended by multi and wideband base station antennas for carrier aggregation. Massive MIMO is a kind of beam forming antenna to enhance SNR or C/I by steering high gain antenna beam. The pico cell is prepared for very high traffic area by short range high data speed communication systems. This talk presents antenna technologies used in 5G system after brief introduction of cellular base station antenna history. In addition to the base station antenna development, smart phone will involve multi-antenna systems to enhance the channel performance and beam forming is also expected for user terminals. Antenna spaces are very limited in recent smart phones, and we need to use chassis antenna modes for built-in antennas. The second topic is the development of built-in smart phone antennas for 5G. Active integrated antennas introduced in base station and smart phone do not provide test ports in measurement. Over the air tests, mandatory for 5G antenna system, are given by spherical scanning to measure all antenna information, fading emulator to generator artificial propagation environment, quasi-plane wave generator to reduce chamber site and etc. These examples are discussed in detail and the challenge of using very near and near field measurement are also presented.

Title: “Satellite Communications Antennas”
21st century has seen several new satellite services such as local-channel broadcast for direct broadcast satellite service (DBS), high capacity K/Ka-band personal communication satellite (PCS) service, hosted payloads, mobile satellite services using very large deployable reflectors, high power hybrid satellites etc. All these satellite services are driven by the operators need to reduce the cost of satellite and pack more capability into the satellite. Antenna sub-system design, mechanical packaging on the spacecraft, and RF performance become very critical for these satellites. System requirements that drive the antenna designs will be presented initially with brief introduction to satellite communications.
Practical designs for satellite communications using contoured beams, multiple spot beams, and reconfigurable beams will be presented. Multiple beam antenna (MBA) concepts and their advantages compared to conventional contoured beams will be introduced. Various designs of the MBA for DBS, PCS, and MSS services will be discussed along with examples. Advances in multi-band antennas covering multiple bands will be presented. Brief introduction to antenna test and qualification for space applications will be given. Future trends in the satellite antennas will be discussed. At the end of this talk, engineers will be exposed to typical requirements, designs, hardware, software, and test methods used for satellite antenna systems.

Title: “Current Trends and Grand Challenges in Computational Electromagnetics for High-Resolution Functional Neuroimaging”
Abstract: In the words of Nobel winner neurologist Rita Levi-Montalcini: “The study of the brain is the most important challenge that human beings have ever faced and the Socratic motto of our times should become: know your brain”. Brain and neuroactivity are inarguably characterized by a stunning complexity: several billion neurons at the microscopic level matched by strongly varying and fuzzy-behaving material properties at the macroscopic level. This notwithstanding, the challenge of brain analysis, mapping, imaging, and modeling has been embraced by many multidisciplinary scientific communities worldwide, it has been targeted by two of the largest funding schemes in the United States and Europe, and it has become a very popular topic of both Earth and Brain hemispheres. Complexity, however, calls for complexity and it is not surprising that every discipline that tackles its own share of the “brain challenge” is obliged to show-off the best of its arsenal. When it comes to Computational Electromagnetics this arsenal is peculiarly rich! This is especially true when the target is functional neuroimaging: the mapping and modeling of the electro-chemical neuroactivity and of the associated brain connectivity. This talk will offer a broad overview of Computationally Empowered Neuroimaging strategies, i.e. technologies for brain diagnostics, therapy, and interaction where computational power, advanced algorithmics, and ad-hoc platforms have paved the way for exciting new discoveries, therapeutic advances, and mind-blowing (literally) applications. Current trends and open Grand Challenges will be delineated together with past achievements and current research efforts even in the framework of the ERC project “321”. Without over-indulging in technicalities, this talk will present discoveries at the theoretical and experimental level always in combination with their promising applications in diagnostics, mind-machine interfaces and in therapeutic neurofeedback. The latter (Socrates would love it!) is as near as we can get today to “knowing our own brain”.
