Electrically Tuned Microwave Devices Using Liquid Crystal Technology

Electrically Tuned Microwave Devices Using Liquid Crystal Technology

An overview of liquid crystal technology for microwave and millimeter-wave frequencies is presented. The potential of liquid crystals as reconfigurable materials arises from their ability for continuous tuning with low power consumption, transparency, and possible integration with printed and flexib...
