One can manipulate waves and fields with materials. Metamaterials, which are specially engineered materials with unconventional wave properties, can tailor and sculpt waves in extreme manners. Such “Extreme Wave Platforms” can exhibit unusual functionalities with exciting potential applications. In my group, we have been exploring a variety of topics in extreme metamaterials and extreme wave-matter-interaction platforms that provide unprecedented features and unusual properties. For example, we have designed materials that can be utilized to conduct analog computing with waves, achieving functionalities such as solving integral equations with waves. As another example, we have introduced and developed structures with effective refractive index near zero, leading to a whole new set of possibilities in wave-matter interaction. The extreme in dimensionality, as another example, can be utilized in one-atom-thick structures such as graphene, which can function as the thinnest possible waveguides. Moreover, judiciously designed nanostructures can act as “lumped” circuit elements for light. And there are more. In this talk, I will present some of our ongoing work on wave-matter interaction in extreme platforms and I will discuss how “extreme materials” and ”extreme waves” can provide useful and exciting platforms for information processing, imaging, sensing and some other wave-based functionality.

The role of Electromagnetic (EM) fields in our lives has been increasing. Communication, remote sensing, integrated command/ control/surveillance systems, intelligent transportation systems, medicine, environment, education, marketing, defense are only a few areas where EM fields have critical importance. We have witnessed the transformation from Engineering Electromagnetics to Electromagnetic Engineering for the last few decades after being surrounded by EM waves everywhere. Among many others, EM engineering deals with broad range of problems from antenna design to EM scattering, indoor–outdoor radiowave propagation to wireless communication, radar systems to integrated surveillance, subsurface imaging to novel materials, EM compatibility to nano-systems, electroacoustic devices to electro-optical systems, etc. The range of the devices we use in our daily life has extended from DC up to Terahertz frequencies. We have had both large-scale (kilometers-wide) and small-scale (nanometers) EM systems. Large portion of these systems are broadband and digital, and have to operate in close proximity that results in severe EM interference problems. Engineers have to take EM issues into account from the earliest possible design stages. This necessitates establishing an intelligent balance between strong mathematical background (theory), engineering experience (practice), and modeling and numerical computations (simulation).
This keynote speech aims at a broad-brush look at certain challenges that confront wave-oriented EM engineering in the 21st century, in a complex computer and technology-driven world with rapidly shifting societal and technical priorities.

Antennas for Wireless Communications and other Applications:
Recent Advances and Future Trends
Many aspects of our lives and economies are becoming fundamentally dependent on wireless technology in a manner that they were not before. This trend is exemplified by the current massive investment in future endeavours, such as 5G technology. Many in IEEE believe 5G will become the cornerstone of future wireless networks, enabling fundamentally new applications such as the internet of things (IOT), with its anticipated billions of devices laden with embedded sensors. A common denominator in many of the new wireless applications is the antenna systems, which form the “eyes and ears” of many sensors. New developments for advancing the state of the art in antenna technology and associated microwave and millimeter wave circuits to meet future challenges will be needed.
This talk will address some current and new emerging directions of research in antenna systems. This includes new fundamental approaches and methodologies for antenna analysis and design, the near fields’ spatial structures around antenna systems and mutual coupling considerations. New findings about the electromagnetic energy around antenna systems, and possible implications on future antenna systems design, in what is expected to be an increasingly crowded electromagnetic environment are presented..

An Overview of Frequency Diverse Array (FDA) Radar Concepts
Basic Concepts of LFDA
Basic Concepts of FMCW-FDA
Basic Concepts of Circular FDA
2D angular space scanning FDA
Discrete scanning FDA
Low energy-time product (Least Action) property of FDA
Radar examples and comparison with Phased Array radar
FDA based radars should be based on T/R module technology and Direct Digital Synthesis Oscillators. Then, they are superior to Phased Array T/R module based radars which are now a subset of FDA based radars. FDA radars are more suitable to cognitive TX actions then Phased Array radars. From the Electronic Warfare and clutter rejection point of view FDA radars have exclusive properties.
This short tutorial aims at revealing the very basic mathematical and physical properties of FDA radars in the simplest way to open ways to explore them for particular applications.
