Defected Ground Structure: Fundamentals, Analysis, and Applications in Modern Wireless Trends

International Journal of Antennas and Propagation, 2017
Slots or defects integrated on the ground plane of microwave planar circuits are referred to as Defected Ground Structure. DGS is adopted as an emerging technique for improving the various parameters of microwave circuits, that is, narrow bandwidth ...

High-Resolution Spectrometer-on-Chip Based on Digital Planar Holography

IEEE Photonics Journal, 2011
Digital planar holography enables the creation of a new generation of integrated photonic circuits with desired transfer function. We give here, for the first time, the basis for designing computer-generated planar holograms and demonstrate their ...

Even circuits in planar graphs

Journal of Combinatorial Theory, Series B, 1981
AbstractWe prove that a planar graph can be partitioned into edge-disjoint circuits of even length, if and only if every vertex has even valency and every block has an even number of edges.

Systematic configuration of coarsely discretized 3D EM solvers for reliable and fast simulation of high-frequency planar structures

, 2013
Accurate simulation of microstrip and other planar structures at very high frequencies usually requires employing full-wave electromagnetic (EM) solvers. For planar circuits, 2.5D EM solvers are especially suited and easy to configure.
