Design, Modeling and Synthesis of Negative Group Delay IL-Shape Topology
IEEE Access, 2019 This paper introduces a negative group delay (NGD) theory of passive topology presenting “IL”-shape geometry. The two-port topology is comprised of a coupled line with an open- and stub-loaded terminations.

Supersymmetry in quantum optics and in spin-orbit coupled systems [PDF]
, 2014 Light-matter interaction is naturally described by coupled bosonic and fermionic subsystems. This suggests that a certain Bose-Fermi duality is naturally present in the fundamental quantum mechanical description of photons interacting with atoms.

Strong Coupling beyond the Light-Line [PDF]
ACS Photonics, 2020 Strong coupling of molecules placed in an optical microcavity may lead to the formation of hybrid states called polaritons; states that inherit characteristics of both the optical cavity modes and the molecular resonance. Developing a better understanding of the matter characteristics of these hybrid states has been the focus of much recent attention ...

A Compact Single-Layer Ultra-Wideband Phase Shifter Using Weakly Coupled Lines
IEEE Access, 2019 This paper presents a novel compact single-layer ultra-wideband phase shifter using weakly coupled lines, which contains a main line and a reference line. The basic equations of this phase shifter are calculated based on the even-odd mode theory.

A two-step perturbation technique for nonuniform single and differential lines [PDF]
, 2013 A novel two-step perturbation technique to analyze nonuniform single and differential transmission lines in the frequency domain is presented. Here, nonuniformities are considered as perturbations with respect to a nominal uniform line, allowing an ...

Super High-Selectivity Fifth-Order Bandpass Filter with Twelve Transmission Zeros [PDF]
Radioengineering, 2018 A fifth-order bandpass filter (BPF) with super high selectivity using three pairs of coupled lines and two open stubs is proposed. Twelve transmission zeros (TZs) from 0 to 2f_0 (f_0 denotes center frequency of the passband) and five transmission poles ...
