SUMMARY:Surface Electromagnetics: Physics Exploration and Engineering Applications
DESCRIPTION:Abstract: From frequency selective surfaces to Huygens metasurfaces\, novel electromagnetic surfaces have been emerging in both scientific exploration and engineering applications. Many intriguing phenomena occur on these surfaces\, and novel devices and applications have been proposed accordingly\, which have created an exciting paradigm in electromagnetics\, the so-called “Surface Electromagnetics (SEM)”. This presentation will review the development of various electromagnetic surfaces\, as well as state-of-the-art concepts and designs. The fundamentals of SEM will be summarized and the frontier topics will be prospected\, including their promising applications in microwaves\, THz\, and optic regimes.

SUMMARY:IEEE Antennas and Propagation Society Distinguished Lecture - Prof. Levent Sevgi
DESCRIPTION:EM diffraction is critical in many applications including antennas and propagation. Understanding and visualizing EM wave – object interaction is crucial in designing new antenna systems\, in predicting path losses through complex propagation paths\, etc. In order to do that wave pieces such as diffracted waves\, Fringe waves\, etc.\, should first be studied on canonical structures. Then\, complex objects can be investigated by using HFA as well as numerical methods in hybrid form intelligently.  EM wave scattering from waves – objects interaction has long been investigated. Interesting wave phenomena\, diffraction\, occur when objects have sharp edges and tips. Methods known as High Frequency Asymptotics\, such as Geometric optics (GO)\, Physical Optics\, (PO)\, Geometrical Theory of Diffraction\, (GTD)\, Uniform Theory of Diffraction (UTD)\, Physical Theory of Diffraction (PTD) and Theory of Edge Diffraction (TED) have been successfully applied to variety of EM problems. Recently\, numerical methods\, such as Finite Difference time Domain (FDTD)\, Method of Moments (MoM) and Finite Element Method (FEM) have also been used in modeling EM diffraction. These powerful methods\, together with novel approaches\, have shown to be successful not only in modeling EM diffraction but also in distinguishing wave pieces such as scattered waves\, diffracted waves\, Fringe waves\, etc.\, which is very important in visualizing and understanding complex wave – object interaction.  This talk will review all these approaches\, use recently developed EM virtual tools and present comparisons through canonical examples.
