A Tunable Metamaterial Resonator Using Varactor Diodes to Facilitate the Design of Reconfigurable Microwave Circuits

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2016
In this brief, we designed, constructed, and analyzed a frequency-tunable metamaterial resonator. The proposed design consists of an S-shaped resonator, a ground frame, and a feeding transmission line.

Rapid Multi-Objective Simulation-Driven Design of Compact Microwave Circuits

IEEE Microwave and Wireless Components Letters, 2015
A methodology for rapid multi-objective design of compact microwave circuits is proposed. Our approach exploits point-by-point Pareto set identification using surrogate-based optimization techniques, auxiliary equivalent circuit models, and space mapping

Hexagonal boron nitride as a low-loss dielectric for superconducting quantum circuits and qubits

Nature Materials, 2021
Dielectrics with low loss at microwave frequencies are imperative for high-coherence solid-state quantum computing platforms. Here we study the dielectric loss of hexagonal boron nitride (hBN) thin films in the microwave regime by measuring the quality ...
