Fast Full-Wave Solution for Analysis of Circular-to-Rectangular-Waveguide Multiport Junction
Fast full-wave solution for accurate analysis of circular-to-rectangular-waveguide multiport junction is presented. The solution is based on the mode-matching method. The new solution scheme is proposed and verified
Rectangular waveguide diplexers with a circular waveguide common port
Design of rectangular waveguide diplexers with a circular waveguide common port is presented. Ridged H- and E-plane circular-to-rectangular-waveguide T-junctions are proposed as an optimum diplexing manifold. Full-wave optimization is used in the diplexer design. Ka-band H- and E-plane rectangular waveguide diplexers with a circular waveguide common port are designed. Measured results are in good agreement with computed results. The sensitivity of the diplexer performance with respect to the manufacturing tolerance is examined through tolerance analysis.
Ground Fault Protection for Electric Utility Generating Station Medium Voltage Auxiliary Power Systems
Most generating station designs have medium voltage auxiliary power systems with low resistance grounded neutrals.1 In order to provide even higher reliability, the auxiliary power distribution system configurations supply increasingly redundant process equipment.
