Abstract: MZI using MMI couplers with a structure that uses an aperture to reduce the size was fabricated. The experimental results of the MZI, which is using MMI extremely smaller than the previous ...
Abstract: In this work, a novel full W-band waveguide reflection-based adjustable attenuator (WRAA) based on quadrature hybrid couplers (QHCs) is presented. The attenuator consists of input and output ...
