Microwave imaging has long been recognized as a viable approach for medical applications. Nonlinear electromagnetic inverse scattering methods are the key enablers of such applications. These imaging systems are essentially multistatic (or tomographic) radars, allowing for noninvasive and non-ionizing diagnostics and treatment monitoring. In this short course, we provide a detailed look at both computational methods and measurement systems for high-resolution 3D imaging for these medical applications. We go beyond the traditional diagnostic imaging and consider the use of microwave imaging for near-real-time intra-operative thermal therapy monitoring, which has been a clinical gap when delivering Radio frequency (RF) ablation and hyperthermia treatments. For delivering thermal therapies, a persistent challenge is monitoring the temporal and spatial progression of heat deposition to prevent under- or over-treatment. Given the strong dependence of the permittivity of both healthy and malignant biological tissue on temperature, the efficacy of microwave imaging for monitoring of thermal treatments has gained much attention in the past several years.
In this course, the following topics will be presented:
We will show that by using progressively accelerated inverse scattering methods for estimating tissue dielectric constant, we are able to map the temperature of the 3D treatment domain in near-real time. Several results will be discussed that show successful retrieval of dielectric constant and temperature fields with a precision of 1o C and spatial resolution of sub-cm at a refresh rate of about 1 frame per second, which has the promise of making this technology realistically useful in a clinical setting.

Reflectarrays and transmitarrays have emerged as the new generation of high-gain antennas which have attracted an increasing interest in the antenna/electromagnetic community because of their low-profile, low-mass, and low-cost features. These antennas are a hybrid design, which combines the many favorable features of reflectors, lens, and printed arrays, and offer many notable advantages over traditional reflectors and lens high-gain antennas. The advantages of reflectarrays and transmitarrays make them very desirable for various communication systems, especially those with mobile platforms. Their applications in space exploration, satellite communications, remote sensing, and radar systems are also on the rise, and will continue to increase in the future.
The aim of this short course is to present a comprehensive overview of reflectarrays and transmitarrays system design and state-of-the-art technology. Specifically, the following topics will be addressed:
Recent design and reconfiguration using pixelated reflectarray antennas.
Illustrative examples for several designs that can serve as good references for attendees.
In summary, the presentation will provide the fundamental capabilities and skills required for a researcher interested in the field of reflectarray and transmitarray antennas.

Now-a-days antennas have become an integral and important part of almost any wireless communication system. In the field of antenna engineering, theoretical analysis is of paramount importance in understanding the basics of the antenna radiation characteristics. While the basic concept of antennas is well known, closed form, exact analytical solutions to many antenna problems are not practical and impossible in many cases. Advances in electromagnetic (EM) simulations have significantly impacted the antenna design process by providing exact solutions by solving Maxwell’s equations using numerical methods. It is a common practice now in academia and industry to use various commercially available EM simulation tools for antenna design process. In this short course, we will introduce basics of antenna modeling and simulation process with pros and cons of various numerical methods, such as Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM), Finite Element Method (FEM), Finite Difference Time Domain (FDTD), Physical Optics (PO), Ray Lunching Geometrical Optics (RL-GO), and Uniform Theory of Diffraction (UTD). We will then discuss modeling and simulation of various antenna types, starting from simple configurations such as dipoles and loops and eventually leading to more complicated and practical designs such as microstrip patches and high-gain reflector antennas.
