We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse-magnetic (TM) modes using a bent lower HPW with vertical nanoscale gaps and a straight upper HPW with a horizontal nanoscale gap, respectively, without relying on an additional coupling region.

On the other hand, TM0 mode should be coupled to the right-hand side and converted to TE0 mode at the cross port. In order to achieve an efficient cross-polarization coupling, both horizontal and vertical symmetry need to be broken [8]. Study and Analysis of Power and Polarization Splitting ...

Investigation and Design of a Slotted Slotted waveguide antennas are a class of antenna commonly used in mi-crowave radar applications. Therefore it can be argued that antennas of this type must exhibit propertiesFirst an investigation into the radiating elements is conducted to ascertain their cross- polarization and physical properties. Low Cross-Polarization Slab Waveguide Filter for… In narrow-wall slotted waveguide array, the horizontal polarization (HP) is the co- polarization, while the vertical polarization (VP) is the cross-polarization. Slotted waveguide array is widely used in radar system, and the high level cross polarization reflects the effect of radar antenna. Optical Polarization Filters and Splitters Based on…

Vertically integrated waveguide polarization splitters light into two waveguide outputs; one for each orthog-onal polarization. The splitting is typically in the horizontal plane for use in conventional two-dimensional (2-D) integrated optics. Vertical polarization splitters, on the other hand, split the polarization vertically into two different levels of stacked 2-D integrated optical circuits. Design of a compact polarization splitter composed of a
slots on the broad wall will produce a field with vertical polarization, while transverse slots on the narrow wall will produce horizontal field polarization [1]. For each design, the polarization depends upon the specific antenna use. The HFSS is a software package analysis modeling and analysis of 3 dimensional structures. HFSS utilizes a 3D
