TE Waves in Arbitrary Periodic Slow-wave Structures with Rectangular Grooves
Journal of Infrared, Millimeter, and Terahertz Waves, 2009 The dispersion characteristics of the transverse electric modes in a waveguide with circular cross-section and periodic rectangular surface corrugations with smoothed edges are examined by the space harmonic method. The whole structure is divided into two regions, one in the propagation area and one inside the grooves.

A 2-D Fully Polarized Van Atta Array Based on Wide-Beam Tri-Polarized Antennas
MicromachinesThis paper proposes a 2-D fully polarized Van Atta array, which consists of four tri-polarized antenna elements. The tri-polarized antenna element comprises a monopole antenna and a low-profile microstrip antenna that widens the beam by folding four ...

Correction of the excitation equations for hollow waveguides
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 The traditional excitation equations are based at the representation of excitating by extraneous sources field in form the sum of own waves TE ( H ) and TM ( E ) of the hollow waveguide, which transverses components form the complete basis in class of ...
