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 ...

Effects of inter-resonator coupling in split ring resonator loaded metamaterial transmission lines
(American Institute of Physics, 2014)
This paper investigates the effects of inter-resonator coupling in metamaterial transmission lines loaded with split ring resonators (SRRs). The study is performed from Bloch mode theory applied to the multiport equivalent ...

Transmission through stacked 2D periodic distributions of square conducting patches
(American Institute of Physics, 2012)
In this paper, we study the transmissivity of electromagnetic waves through stacked two-dimensional printed periodic arrays of square conducting patches. An analytical circuit-like model is used for the analysis. The model ...

Common-mode suppression in microstrip differential lines by means of complementary split ring resonators: Theory and applications
(Institute of Electrical and Electronics Engineers, 2012)
This paper is focused on the application of complementary split-ring resonators (CSRRs) to the suppression of the common (even) mode in microstrip differential transmission lines. By periodically and symmetrically etching ...

Accurate circuit modeling of fishnet structures for negative-index-medium applications
(Institute of Electrical and Electronics Engineers, 2016)
Metallic plates with a two-dimensional (2D) periodic distribution of sub-wavelength apertures are known to exhibit extraordinary transmission of electromagnetic waves. Stacking two or more of such plates gives place to the ...
