Symmetrical property of the dyadic Green’s function for rectangular cavity

【摘要】 <正> The problem about the complete form of the dyadic Green’s function is one of thefundamental problems in electromagnetic field and also a controversial one for a long time.Detailed derivations of several alternative representations of the dyadic Green’s function inmany systems were given in Tai’s famous book.However,someone pointed out this formof the dyadic Green’s function was not complete,then an isolated singular term was later更多还原
