The silicon cross-slot waveguide presented here is taken from an article from Helsinki University of Technology [1], featuring FIMMWAVE simulations. The paper also presents results for waveguide geometries with angled sidewalls. Frontiers | Low-Loss Slot Waveguides with Silicon (111)… We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform.This slow etching of the (111) plane can also be used to precisely control the slot width by simply optimizing theIn most applications, the slot waveguides are cladded with low index materials, such as polymers (Koos... A cavity-backed coplanar waveguide slot antenna Polarization Bandwidth Dual frequency operation Spurious radiation Isolation between radiating elements Frequency scanning Cross- polarization level End-fire antenna.Inspecting the real input impedance directly gives a good depiction as to how slot width will control the input impedance.

The polarization of a slot antenna is linear. The fields of the slot antenna are almost the same as the dipole antenna, but the field’s components are interchanged: a vertical slot has got an horizontal electric field; and the vertical dipole has got a vertical electrical field.

Most waveguides support modes of two independent polarizations, with either the dominant magnetic (quasi-TM) or electric (quasi-TE) field component along the transverse (horizontal) direction. For most applications, it is preferable that the waveguides operate in a single-mode regime for each polarization.
