Abstract
The use of nano-structured elements in the fabrication of micro-optical subwavelength components requires a fully vectorial solution to Maxwell's curl equations. In this paper, we compare the results generated by two of the main methods used in the solution of the curl equations, the Fourier Modal Method (FMM) and the Finite Difference Time Domain (FDTD) method. We address the computational issues surrounding the accurate modelling of nano-structured elements (with features in the 10nm-100nm range) for a range of micro-optical elements, e.g. cylindrical lenses, photonic bandgap reflectors and polarisation dependent beamsplitters. Finally, we show the experimental verification of the nano-structured designs using microwave radiation.
