Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next ...

Abstract: In this paper, we propose and validate a new approach for increasing the optical bandwidth of waveguide grating couplers by using a center-symmetric grating structure. Our results ...

Abstract: Ensuring adequate wireless coverage in upcoming communication technologies such as 6G is expected to be challenging. This is because user demands of higher data rate require an increase in ...
