Wave Channelling in Higher Order Anisotropic Tunable Meshes with Capacitive Control

An analytical and numerical analyses of three types of the mesh unit cell configurations comprised of double series, double parallel and mixed parallel and series L-C circuits as the arms of a periodic grid have been performed. The results of detailed study show that control of frequency selective wave channeling and the type of channeled wave (forward or backward) on the mesh can be achieved by varying capacitance only. These findings are of particular importance for implementation of tunable meshes for beam steering and phase compensation applications
