Coplanar and microstrip oscillators in SiGe SIMMWIC technology [PDF]
2001 IEEE MTT-S International Microwave Sympsoium Digest (Cat. No.01CH37157), 2002 Oscillators in SiGe SIMMWIC HBT technology have been realized in coplanar and a newly developed microstrip environment. Coplanar 24 GHz LC oscillators show 8.7 dBm output power and a phase noise of -99 dBc/Hz @ 100 kHz offset. Coplanar 27 GHz VCO's yield 12.5 dBm output power and a tuning range of 1.28 GHz.

Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
