COMPACT POLARIZATION PLANE ROTATOR AT A DEFINED ANGLE IN THE SQUARE WAVEGUIDE [PDF]
Радиофизика и электроника, 2017 We have studied the possibility of designing compact polarization plane rotator electromagnetic waves on the basis of the structures with dihedral symmetry, and formed by 5-resonant slotted apertures with rectangular irises. The proposed structure allows

Advanced Photonics 2013, 2013 We present an easily fabricated waveguide prism for the terahertz (THz) frequency range. The prism is made of polypropylene and uses waveguide dispersion to spatially separate frequencies over the range of 0.1 to 0.7 THz. The diffraction properties of the prism were determined using electromagnetic field simulations and the waveguide parameters were ...
