A Novel Synthetization Approach for Multi Coupled Line Section Impedance Transformers in Wideband Applications

Applied Sciences, 2022
In this paper, a novel synthetization approach is proposed for filter-integrated wideband impedance transformers (ITs). The original topology consists of N cascaded coupled line sections (CLSs) with 2N characteristic impedance parameters.

Coherent output of photons from coupled superconducting transmission line resonators controlled by charge qubits

, 2008
We study the coherent control of microwave photons propagating in a superconducting waveguide consisting of coupled transmission line resonators, each of which is connected to a tunable charge qubit. While these coupled line resonators form an artificial
