A two-dimensional (2-D) (azimuth and elevation) beam-steering partially reflective surface (PRS) antenna is proposed in this letter. It consists of a probe-fed square patch antenna acting as the ...

We introduce a simple geometry for slow-wave structures (SWSs) in sheet-beam traveling-wave tubes (TWTs). The staggered microstrip grating SWS is a space harmonic structure with geometry and bandwidth ...

In this paper, a comprehensive dynamical analysis of porous-reinforced carbon nanotube (CNT) nanocomposite beams on viscoelastic foundations is presented. Using a three-unknown shear beam theory, the ...
