Non-reciprocal devices that allow a signal to be transmitted only in one direction are important for full-duplex communications. Due to the requirements of miniaturized systems. there has been an increase interest in non-magnetic non-reciprocal devices in recent years. Based on parity-time ( PT ) symmetric inductors-capacitors ( LC ) resonators. https://www.nacrack.com/mega-pick-As-for-Me-and-My-House-Wall-Decal-in-Hebrew-Yahauh-flash-find/
