Abstract:
We consider Green's function for layered system. We express it in terms of the well-known scalar $s$ and $p$ ones. For a single NIM layer in vacuum and with a single dispersive Lorentz form for equal electric and magnetic permeabilities $\varepsilon$($\omega$) and $\mu$ ($\omega$), we obtain an explicit form for Green's function. Also we find Green's function for multilayered system and obtain recurrence relations for its coefficients.
