Abstract: Metal nanostrip array for light transmission enhancement in the nanoslit is studied using a finite-difference time-domain method (FDTD). The strips with uniform shape are placed on upper side of a metal film with the nanoslit fabricated in it. It is found that the transmission efficiency can be promoted with an optimization of the strip. Effects of the single strip on the promotion are discussed in detail, a Fabry-Perot resonance model is competent for well understanding the phenomena.
