Eigenanalysis of canonically shaped structures served as an indispensable tool the conception and establishment of a plethora of electromagnetic structures from filters to cavities and antennas. However, the recent evolution of radio systems and wireless communications ask for the design of multifunctional rf front-ends in compact form and conformally integrated on mobile devices. The eigen-analysis...
The current work is the theoretical framework of the Research Project “Thales” entitled: “Development of electromagnetic simulation and design tools for digitally controlled and multifunctioning RF-microwave stages and subunits which retain characteristics-specification supporting Software Defined (SDR) and cognitive Radios (CR)”. Thus, a review of the analytical and numerical eigenenalysis tools...
Computing of wave propagation and radiation through periodic band gap structures and their unique electromagnetic features attracted a huge research interest during the last decades. These features enabled the development of novel metamaterials and were exploited in frequency selective surfaces, phased arrays and numerous electromagnetic bandgap applications. Moreover, the metamaterials including...
An eigenanalysis of an array of periodically located wires covered with axially magnetized ferrites is presented. The interest in this structure stems from our previous study which revealed that such a wire may support backward surface and possibly backward leaky waves. These possibilities are examined herein by using our two - dimensional curvilinear frequency domain finite difference (FDFD) toward...
