【Abstract】 Based on the rigorous electromagnetic fields theory,the eigenfunction solutions of radiation fields for an electric dipole antenna with a shell of left hand material(LHM)are given in this paper.The radiation power is calculated through the eigenfunction solutions.Compared with the radiation fields of free space,the calculated results show that the application of left hand material can increase the radiated power gain.This characteristic for LHM was also validated by the microwave circuit theory.更多还原
