Omega transmission lines [PDF]

open access: yes2013 7th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics, 2013
In this paper, we show how bi-anisotropic media with omega-type response can be realized using periodically loaded transmission lines. General conditions for the needed unit cell circuit block are derived. Also, an implementation is shown and analyzed.

A novel superimposed component‐based protection method for multi‐terminal transmission lines using phaselet transform

open access: yesIET Generation, Transmission & Distribution, 2023
This paper presents a novel protection method for transmission lines that estimates the superimposed component phasor using phaselet transform. The phaselet transform computes the phasors over variable‐lenfgth data window at the instant of a fault, so it
