Non-uniform sinusoidally modulated half-mode leaky-wave lines for near-field focusing pattern synthesis
(Institute of Electrical and Electronics Engineers, 2015)
A novel non-uniform sinusoidally modulated half-mode microstrip structure with application to near-field focused leaky-wave radiation in the backward Fresnel zone is proposed. First, it is presented a dispersion analysis ...

Broadband Extraordinary Transmission in a single sub-wavelength aperture
(Optical Society of America, 2010)
Coordinate transformation is applied to design an all-dielectric device for Extraordinary Transmission (ET) in a single sub-wavelength slit. The proposed device has a broadband feature and can be applied from microwave to ...

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 ...

Analytical wideband model for strip/slit gratings loaded with dielectric slabs
(Institute of Electrical and Electronics Engineers, 2012)
This paper presents a fully analytical model to determine the transmission and reflection properties of planar 1-D distributions of metal strips or slits made in thin metal screens. In contrast with other analytical or ...

Analytical Multimodal Network Approach for 2-D Arrays of Planar Patches/Apertures Embedded in a Layered Medium
(Institute of Electrical and Electronics Engineers, 2015)
A fully analytical multimodal equivalent circuit is presented for the modeling of the scattering of an obliquely incident plane wave by a two-dimensional (2-D) periodic array of metallic patches (or apertures in a metallic ...

Study and Design of a Compact Parallel Coupled Microstrip Band-Pass Filter for a 5 GHz Unlicensed Mobile WiMAX Networks
(International Journal of Science and Technology, 2013)
In this paper, a compact parallel coupled microstrip band-pass filter (BPF) is used to design a wideband third order of the Tschebyshev elements for an unlicensed WiMAX technology. Some techniques based on the parametrical ...

Enhanced transmission with a graphene-dielectric microstructure at low-terahertz frequencies
(American Physical Society, 2012)
Here, we report on the transmissivity of electromagnetic waves through a stack of monolayer graphene sheets separated by dielectric slabs at low-terahertz frequencies. It is observed that the multilayer structure possesses ...
