Single-layer dipole arrays for general transformations of plane waves

In this presentation we review our recent studies of arrays of electrically small particles designed to perform general transformations of normally incident plane waves. We show that single-layer dipole arrays can, for example, act as matched polarization transformers, perfect absorbers, high-impedance surfaces, ideal isolators and other devices. The analysis reveals what physical mechanisms can be used to realize a desired functionality, and the developed synthesis methodology gives a way to design inclusions to realize the devices.
