Journal ArticleDOI
Material Characterization Using Complementary Split-Ring Resonators
TL;DR: A microwave method based on complementary split-ring resonators (CSRRs) is proposed for dielectric characterization of planar materials and eliminates the extensive sample preparation procedure needed in resonance-based methods.
Journal ArticleDOI
Mutual Coupling Reduction Between Microstrip Patch Antennas Using Slotted-Complementary Split-Ring Resonators
TL;DR: In this paper, a novel structure based on complementary split-ring resonators (SRRs) is introduced to reduce the mutual coupling between two coplanar microstrip antennas that radiate in the same frequency band.
Book ChapterDOI
The Finite-Difference Time-Domain Method
TL;DR: The Finite-Difference Time-Domain method provides a direct integration of Maxwell’s time-dependent equations and is especially wellsuited for most EMI/EMC problems in which a wide frequency range is intrinsic to the simulation.
Journal ArticleDOI
A novel power plane with integrated simultaneous switching noise mitigation capability using high impedance surface
TL;DR: In this paper, a novel technique for suppressing power plane resonance at microwave and radio frequencies is presented, which consists of replacing one of the plates of a parallel power plane pair with a high impedance surface or electromagnetic band gap structure.
Journal ArticleDOI
Electromagnetic interference (EMI) reduction from printed circuit boards (PCB) using electromagnetic bandgap structures
S. Shahparnia,Omar M. Ramahi +1 more
TL;DR: In this paper, an effective method for suppressing PCB radiation from their power bus over an ultrawide range of frequencies by using metallo-dielectric electromagnetic band-gap structures was introduced.
