Abstract: In this letter, a rectangular waveguide structure with phase-shifting and filtering capabilities is presented for satellite communications. Through adding protruding stripes along the narrow ...
Abstract: A p-i-n diode waveguide phase shifter (PS) with a power handing capacity over 1 MW and a response time within 100 ns is proposed at the S-band. By inserting a conventional switchable ...
A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
