The radiation patterns of perturbed two dimensional parabolic reflector fed by a slotted circular cylindrical waveguide for both the TE and the TM modes are examined. The analysis is carried out using ...

The Global Times learned Tuesday from the Deep Space Exploration Lab (DSEL) that prototypes of the in-situ lunar soil 3D ...

In the reflector-based compact antenna test range (CATR), the aperture usage is one of our most concerned problems. Higher aperture usage means that in a CATR with the same aperture reflector, a ...
