Photonic Integrated Circuits for Microwave Astronomy
Inventions, 2023 One of the main objectives of cosmology is the measurement of the Cosmic Microwave Background (CMB) polarization and, in particular, the so-called B-modes, which could demonstrate the existence of the primordial gravitational waves generated at the early

Implementation of Microwave Circuits Using Stereolithography. [PDF]
Polymers (Basel), 2022 In this work, the use of additive manufacturing techniques through stereolithography for the manufacture of high-frequency circuits and devices is presented. Both the resin and the 3D printer used in this research are general-purpose commercial materials, not specifically intended for the implementation of microwave networks.

Nonreciprocal Reconfigurable Microwave Optomechanical Circuit [PDF]
2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2017 AbstractNonreciprocal microwave devices are ubiquitous in radar and radio communication and indispensable in the readout chains of superconducting quantum circuits. Since they commonly rely on ferrite materials requiring large magnetic fields that make them bulky and lossy, there has been significant interest in magnetic-field-free on-chip alternatives,

System and Circuit Models for Microwave Antennas [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2006 This paper describes how circuit and system models are derived for antennas from measurement of the input reflection coefficient. Circuit models are used to optimize the antenna performance and to calculate the radiated power and the transfer function of the antenna. System models are then derived for transmitting and receiving antennas.

CAD techniques for microwave circuits [PDF]
Electronics & Communication Engineering Journal, 1996 In little more than 10 years computer-aided design (CAD) of microwave circuits has moved from dumb terminals on mainframe computers to PCs, and now to powerful RISC workstations. Commercial CAD software now integrates the various stages of microwave circuit design: schematic capture, simulation and layout.

Electric circuit model of microwave optomechanics [PDF]
Journal of Applied Physics, 2021 We report on the generic classical electric circuit modeling that describes standard single-tone microwave optomechanics. Based on a parallel RLC circuit in which a mechanical oscillator acts as a movable capacitor, derivations of analytical expressions are presented, including key features such as the back-action force, the input–output expressions ...

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
