Spatial angular filtering by FSSs made of chains of interconnected SRRs and CSRRs
(Institute of Electrical and Electronics Engineers, 2013)
Two frequency selective surfaces (FSSs) made of an infinite set of parallel 1-D chains of interconnected split ring resonators (I-SRRs) and interconnected complementary split ring resonators (I-CSRRs) are studied. The main ...

Simple and compact balanced bandpass filters based on magnetically coupled resonators
(Institute of Electrical and Electronics Engineers, 2015)
A simple strategy is proposed to design differential-mode bandpass filters with good common-mode (CM) rejection using simple resonators. Specifically, the CM rejection is enhanced by using conventional open-loop resonators ...
