WMG: Recent Advances in Phase Change Materials (PCM) Switch Technology and its Microwave and mm-Wave Applications

Abstract
Phase-Change Material (PCM) RF switches are emerging as a breakthrough technology for reconfigurable microwave and mm-wave circuits. With their non-volatile operation, low insertion loss, and high power-handling capability, PCM switches offer distinct advantages over conventional alternatives. These properties make them ideal for use in phase shifters, impedance tuners, reconfigurable filters and switchable antenna arrays. At mm-wave frequencies, their scalability and fast response unlock new possibilities in adaptive beamforming, dynamic spectrum access, and next-generation 5G/6G wireless, satellite, and radar systems. This workshop will bring together leading experts from industry and academia worldwide to present recent advances and future directions in PCM-based RF technologies including coverage of device concepts, circuit integration, and application case studies. It aims to foster cross-disciplinary dialogue and broaden the community’s understanding of this promising technology for future mm-wave communication platforms.
