The objective of my proposed research is to use electromagnetic principles for developing mathematical tools for investigating the wave interactions with surrounding media, and to enable the design of electromagnetic devices, such as antennas, sensors, and other components for applications in emerging areas in science and engineering. It will have several groundbreaking advances in communication and remote sensing. I will conduct research on the development of low loss engineered materials. The conductor losses have been “the source of all evil” in radio science and anything dealing with electromagnetic waves, and created the dream of superconductivity. Recently, in a modest way, I have demonstrated loss reduction in layered structures, and this research will investigate it in detail, using physical principles, and develop mathematical models for its minimization. Conductive loss reduction will launch a new wave of innovation in many areas of science and technology. I propose to advance my research on virtual antenna arrays, which replaces multiple antennas with only one, with the aid of electromagnetic modeling and signal processing. With further development, I intend to investigate its applications in synthetic aperture radars and satellite observations, using high gain antennas. I will also study applications where device miniaturization has a transformative impact, by hardware minimization, or replacement with software. I plan to further study the electromagnetic response of Arctic sea ice, and develop dedicated algorithms for scattering by its special features, such as frost flowers and brine inclusions. The results of this research will be invaluable for improving our understanding of the sea ice, and predictions by large-scale satellite observations, and sustainable development of the North. I propose investigating the symmetric properties of electromagnetic waves scattered from objects and tissue anomalies. This research will relate the received response to the object’s location, rather than the source contrast, used currently in microwave imaging. Its features will be similar to MRI imaging and the latter’s signal processing can be used to improve the detection and identification of the anomalies.
