The design, assembly, and performance of a prototype 1/spl times/8 free-space switch demonstrator using reconfigurable holograms are reported. Central to the switch fabric is a ferroelectric liquid crystal (FLC) on silicon spatial light modulator (SLM) deposited with a 540/spl times/1 array of highly reflective and planar mirror strips. The input and output(More)

Many thermal issues facing the microwave bipolar industry are discussed, and the application of experimental and modeling techniques is demonstrated for real microwave devices. The liquid crystal transition method of thermal measurement is shown to be useful for modern bipolar devices because the method can determine temperatures with excellent spatial(More)
