Near-field enhanced imaging by a magnetized ferrite slab
(American Institute of Physics, 2005)
This letter demonstrates the near-field imaging enhancement at microwave frequencies of two-dimensional sources by a ferrite slab magnetized to saturation. It is shown that this effect is based on the nonreciprocal ...

Capacitance and Inductance Matrices for Multistrip Structures in Multilayered Anisotropic Dielectrics
(Institute of Electrical and Electronics Engineers, 1987)
In this paper we present a unified variational approach to determine the capacitance and inductance matrices of generalized multistrip systems embedded in a multilayered iso/anisotropic dielectric lossless medium. The ...

Quick Computation of [C] and [L] Matrices of Generalized Multiconductor Coplanar Waveguide Transmission Lines
(Institute of Electrical and Electronics Engineers, 1994)
An enhanced spectral domain quasi-TEM analysis of generalized coplanar waveguide transmission lines (GCPWTL) is presented. The analysis starts from the formulation of a convolution-type integral equation for the electric ...

Design of compact low-pass elliptic filters using double-sided MIC technology
(Institute of Electrical and Electronics Engineers, 2007)
A novel implementation of stepped-impedance low-pass elliptic filters is presented in this paper. The filters are based on the well-known technique of cascading high- and low-impedance sections to simulate the ladder LC ...

Fast full-wave analysis of multistrip transmission lines based on MPIE and complex image theory
(Institute of Electrical and Electronics Engineers, 2000)
The mixed-potential electric-field integral equation is used in conjunction with the Galerkin's method and complex image theory for analyzing a transmission line with multiple strips embedded in different layers of a ...

Differential Lines for Common-Mode Suppression Based in Hybrid Microstrip/CPW Technology
(Institute of Electrical and Electronics Engineers, 2017)
A symmetrical pair of differential microstrip lines implemented in hybrid microstrip/coplanar waveguide (CPW) technology is proposed. Transmission-line models are used to analyze differential-and common-mode responses, ...

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 ...

Multilayered balanced dual-band bandpass filter based on magnetically coupled open-loop resonators with intrinsic common-mode rejection
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
A new dual-band balanced bandpass filter based on magnetically coupled open-loop resonators in multilayer technology is proposed in this paper. The lower differential passband, centered at the Global Positioning System ...

Numerical implementation of the mixed potential integral equation for planar structures with ferrite layers arbitrarily magnetized
(Wiley-Blackwell, 2006)
This work presents a new implementation of the mixed potential integral equation (MPIE) for planar structures that can include ferrite layers arbitrarily magnetized. The implementation of the MPIE here reported is carried ...
