Theoretical and experimental exploration of finite sample size effects on the propagation of surface waves supported by slot arrays
(American Institute of Physics, 2017)
The propagation of surface waves supported by a finite array of slots perforated on a zero thickness perfect electrically conducting screen is studied both experimentally and theoretically. To generate numerical results, ...

Self-complementary metasurface for designing narrow band pass/stop filters
(Institute of Electrical and Electronics Engineers, 2013)
A self-complementary metasurface is studied in this paper. The metasurface is a 2-D periodical arrangement of unit cells formed by a metallic printed split ring resonator and its complementary counterpart. It is demonstrated ...

New absorbing boundary conditions and analytical model for multilayered mushroom-type metamaterials: Applications to wideband absorbers
(Institute of Electrical and Electronics Engineers, 2012)
An analytical model is presented for the analysis of multilayer wire media loaded with 2-D arrays of thin material terminations, characterized in general by a complex surface conductivity. This includes the cases of ...

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 ...

Ultra-compact (80 mm 2) differential-mode ultra-wideband (UWB) bandpass filters with common-mode noise suppression
(Institute of Electrical and Electronics Engineers, 2015)
This paper presents a novel approach for the implementation of balanced ultra-wideband (UWB) bandpass filters with common-mode noise suppression. To a first-order approximation, the differential-mode filter response is ...
