PROJECT TITLE :

Equivalent-Network Analysis of Propagation and Radiation Features in Wire-Medium Loaded Planar Structures

ABSTRACT:

Planar multilayer dielectric structures that embody wire-medium (WM) slabs with vertically aligned wires are studied by means of an effective equivalent transmission-line approach primarily based on the homogenized illustration of the WM layers. Modal properties are thereby retrieved via transverse resonance, whereas radiative properties of elementary sources are calculated via reciprocity. The proposed approach is utilized to indicate the chance of suppressing TEM propagation in WM-loaded parallel-plate waveguides also of achieving wideband radiation from TM leaky modes in partially open configurations. The options thus gained are of interest for the realization of Fabry–Perot cavity antennas with linearly polarized conical patterns and wide-angular scanning ranges. Numerical results obtained with state-of-art simulation software ensure the accuracy and numerical effectiveness of the proposed formulation.
