A. I. Cabuz, A. Nicolet, F. Zolla, D. Felbacq. Effective medium theory for the finite conductivity bed of nails structure. TACONA International Workshop on Theoretical and Computational Nanophotonics, 2009.

Rezumat: We present and illustrate an effective medium theory of the finite conductivity periodic finite wire medium (thebed-of-nails structure). It is constructed using a renormalization approach to obtain the system of equations satisfied by the electromagnetic field and the electric current in the limit of large wavelength-to-period ratio. The model is tested numerically and its domain of validity is characterized using full vector three dimensional finite element calculations. Bed-of-nails structures exhibit large absorption with small reflection while their low fill factor allows considerable freedom to control other characteristics of the metamaterial such as its mechanical, thermal or chemical robustness.
