A Ka-band radial power combiner is proposed using broadband probes and a radial cavity with resistive slots. The broadband probe consists of cylindrical conductors and dielectric spacers. The resistive slots on top and bottom plates of the radial cavity can improve port isolation and control higher order modes. Over the frequency band of 26 to 33 GHz, the return loss of the input port is greater than...
High voltage overhead lines produce intense electric field and induce current in human body which may be hazard to human health. To study electric field of overhead lines and human body, a mixed method utilizing both finite element method and surface charge method is first presented. It can be used to complex structure and open domain. Merged matrix equation is deduced and an example of electric field...
