Time-reversal radar imaging takes advantage of concepts based on time-reversed wave propagation to improve object resolution when these objects are located in a complex environment. There exists a multitude of propagation paths, making their imaging difficult. However, multipath can also be used to enhance the object location and shape. In the case of synthetic aperture radar (SAR) imaging, multipath...
In this paper, we propose a new class of printed designs that emulate anisotropy and phenomena seen only in magnetic media. In contrast to, the proposed printed design utilizes a substrate that incorporates sections of available magnetic materials. Therefore, nonreciprocal wave propagation is realized and asymmetric dispersion diagrams are generated such as those to the right. These asymmetric diagrams...
A microstrip transmission line model is proposed for a new class of photonic crystals which exhibit a degenerate band edge (DBE). The microstrip line model is formed from a pair of coupled and uncoupled lines (one per field component, Ex and Ey) and is the first (to our knowledge) representing propagation within an anisotropic layered medium. Using the standard scattering matrix representation for...
