Dielectric Losses in Dry-Type Insulation of Medium-Voltage Power Electronic Converters
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 Newly available medium-voltage (MV) silicon carbide (SiC) transistors are setting new limits for the design space of MV converters. Unprecedented blocking voltages, higher switching frequencies, higher commutation speeds, lower losses, and high ...

Loss-induced performance limits of all-dielectric metasurfaces for terahertz sensing [PDF]
Phys. Rev. Applied 19, 014009 (2023), 2022 Metasurfaces providing resonances arising from quasi-bound states in the continuum have been proposed as sensors in the THz band due to the existence of strong resonances characterized by high quality factors. Controlling geometrical parameters, the quality factor can be adjusted and, theoretically, designed at will.

Hydrogenated Amorphous Silicon Carbide: A Low-loss Deposited Dielectric for Microwave to Submillimeter Wave Superconducting Circuits [PDF]
Phys. Rev. Appl. 18 (2022) 064003, 2021 Low-loss deposited dielectrics will benefit superconducting devices such as integrated superconducting spectrometers, superconducting qubits and kinetic inductance parametric amplifiers. Compared with planar structures, multi-layer structures such as microstrips are more compact and eliminate radiation loss at high frequencies.
