This session presents new components, structures, and techniques for various microwave applications. One structure is a new type of metasurface that offers broadband polarization conversion for an incident plane wave. Another contribution is a novel design of a microwave circulator that is based on coupled CRLH lines on a ferrite substrate. A new type of slow wave structure based on nanowires that are incorporated into a substrate is presented. The session also presents an insightful examination of the reactive and radiative regimes for a leaky-wave antenna, and discusses a new way to use leaky-wave antennas for beam scanning.

This session provides an exposition of the recent developments on numerical modeling, optimization, and simulation-driven design for microwave engineering. The presented papers cover a variety of topics, including novel techniques for surrogate modeling of microwave passives, methodological advancements in variability analysis in highly-dimensional spaces, cost function formulation for efficient extraction of circuit parameters, as well as applications of surrogate modeling techniques for design optimization and uncertainty quantification of high-frequency components. Theoretical developments are complemented by application case studies.
