The filtering and physical concepts of the nanostructure are discussed using the quasi-static approximation and the circuit model. The optical properties of the proposed nanofilter are investigated using the dispersive finite­difference time-domain method. The spectral response of the filter is tunable in the considered optical range. The model and simulations results agree with the experiments. %> http://ijict.itrc.ac.ir/article-1-293-en.pdf %P 21-27 %& 21 %! %9 Research %L A-10-27-263 %+ Faculty of Electrical Engineering, K. N.
