Traveling Waves and Power Waves: Building a Solid Foundation for Microwave Circuit Theory

open access: yesIEEE Microwave Magazine, 2013
Microwave equivalent-circuit theory is like a grand old building: elegant, carefully crafted, passed from generation to generation, and rooted in history. Traveling waves, the measureable electromagnetic field solutions of Maxwell's equations in a transmission line, form the foundation of the theory.

Theory of Microwave Parametric Down-Conversion and Squeezing Using Circuit QED [PDF]

open access: yesPhysical Review Letters, 2005
We study theoretically the parametric down conversion and squeezing of microwaves using cavity quantum electrodynamics of a superconducting Cooper pair box (CPB) qubit located inside a transmission line resonator. The non-linear susceptibility χ_2 describing three-wave mixing can be tuned by dc gate voltage applied to the CPB and vanishes by symmetry ...
