ion, the DGS reconfigurable filter illustrates that the on-demand electromagnetic characteristics of a device withРmultiple FIPCS-T and GeTe material layers are feasible by controlling each FIPCS-T state in the FIPCS-T array in aРmassive antenna and giant circuit stack systems. The adjustable and controllable characteristics can satisfy many importantРfuture requirements, such as fast beam forming, beam scanning, RF circuit switching, channel multiparameter dynamicРadaptation, and multifunctional RF devices for future wireless communication and radar.РРradio-frequency switch, heating phase-change material, GeTe, indirect heating, reconfigurable, microwave/Рmillimeter-waveРРdoi: 10.1360/TB-2021-1198РР 9
