This paper proposes an H-shaped defected ground structure to reduce the E-plane and H-plane couplings of a <tex>$4\\times 4$</tex> antenna array simultaneously. The mode theory and magnetic current ...

We report SDM transmissions based on DMT and a 4-channel membrane DML-array-on-Si. By simultaneously modulating all lasers, 200G (KP4-FEC) and 400G (SD-FEC) are demonstrated over 425-m MCF with ~6× ...
