Abstract :
It is now becoming possible to model photonics devices via direct solution of Maxwell´s equations. This is because advances in the mathematical methods used for radio-frequency electromagnetic computation, driven by military ´stealth´ requirements, have produced a step increase in computational capability. In this paper we will apply these improved computational tools to the analysis of thin metal sheets with patterns of sub-wavelength holes drilled in.
