Microwave scattering from a broadband depolarizing array of loaded planar chiral particles

Numerical and experimental results on the scattering of an electromagnetic plane wave by an array of novel planar chiral particles are presented in this paper. The geometry of the particles are chosen in order to obtain a depolarization of the scattered wave on a broad frequency band. We also present results corresponding to arrays with the chiral particles connected to passive linear electronic loads. By varying the loads, we demonstrate, theoretically and experimentally, that the properties of depolarization can be electronically controlled. These results suggest a potential application of the studied samples in the design of agile polarization transformers.
