摘要：
The Green's functions are compared for the Maxwell, Beltrami and Helmholtz equations as applied to effective infinite isotropic media, including electromagnetic metamaterials. The Dyadic and scalar Green's functions are calculated based on the 3D and 2D Fourier transforms and the residue theory without using the so-called concept of a negative refractive index.
