Abstract: This work presents a D-band phase shifter which utilizes a one-bit phase inverter (PI), followed by two cascaded reflective-type phase shifters (RTPSs). The PI uses two identical cascode ...

Abstract: In this work, a series of fiber-optic salinity sensors were prepared. The sensing principle of salinity sensor is the changes of reflection coefficient and evanescent wave attenuation with ...
