Investigation of rectangular, uni-directional, horizontally ... slots. Longitudinal slots far from the center or in the sidewall do not form good radiators [13]. 4) Slot Radiation: The ability of a slot to radiate power can be compared to a slot voltage on a transmission line. Slot voltage allows for slots to be modelled as equivalent active shunt admittance on a lossless transmission line. Measurement of the Strength of Electric Fields by Means of ... The microresonators are based on stripline waveguides with vertical and horizontal slots filled with a liquid-crystal material.
