Abstract: |
A novel method of deriving the electromagnetic dyadic Green’s functions in an unbounded, lossless, reciprocal and homogeneous chiral media described by the constitutive relations D=εE+jγB and H=jγE+μ-1B-(ωε)-1γJ is given. The divergenceless and irrotational splitting of dyadic Dirac δ function and Fourier transformation are used to directly obtain the divergenceless and irrotational component of spectral-domain dyadic Green’s functions in chiral media. This method avoids using the dyadic Green’s function eigenfunction expansion technique. The method given here can be generalized to a source-free region and an achiral case. |
