  Selective scattering of red-, green- and blue-light and transmitting other
visible light to achieve transparent projection screen has been proposed
recently based on metallic nanoparticle's localized surface plasmon resonance
(LSPR). However, dielectric (TiO2) substrate/silver (Ag) nanocube structure was
only demonstrated to selectively scatter blue-light in the backward direction.
Given human eyes are sensitive to green-light, it is of interest to find out
how to achieve selective forward-scattering of blue- and red-light and
selective backward-scattering of red-light. In this work, through numerical
simulation, forward and backward scattering properties of dielectric
substrate/Ag (or gold) nanocube structures are investigated. And based on these
properties, three designs are proposed which can achieve selective scattering
of blue- and red-light in forward or backward or both directions.
