3D Band-Absorptive Frequency Selective Rasorber: Concept and Analysis
IEEE Access, 2019 This paper presents a 3D band-absorptive frequency selective rasorber (FSR). Such an FSR is absorptive within a specific band and almost transparent below the absorption band. The definition and evaluation of the band-absorptive FSR is initially provided

Circuit Quantum Electrodynamics [PDF]
Rev. Mod. Phys. 93, 25005 (2021), 2020 Quantum mechanical effects at the macroscopic level were first explored in Josephson junction-based superconducting circuits in the 1980's. In the last twenty years, the emergence of quantum information science has intensified research toward using these circuits as qubits in quantum information processors.

Millimeter-wave interconnects for microwave-frequency quantum machines [PDF]
Phys. Rev. A 96, 042305 (2017), 2017 Superconducting microwave circuits form a versatile platform for storing and manipulating quantum information. A major challenge to further scalability is to find approaches for connecting these systems over long distances and at high rates. One approach is to convert the quantum state of a microwave circuit to optical photons that can be transmitted ...
