We analyze the structure of the vacuum polarization tensor in the presence of a background electromagnetic field in a medium. We use various discrete symmetries and crossing symmetry to constrain the form factors obtained for the most general case. From these symmetry arguments, we show why the vacuum polarization tensor has to be even in the background(More)
In this paper we have presented a moment method analysis of a shunt - series slot fed waveguide broad wall shunt slot radiator. To analyze the circuit Multiple Cavity Modelling Technique (MCMT) has been used. The theory has been validated by the excellent agreement obtained between the MCMT and Ansoft HFSS simulated data.
