Application of numerical dispersion compensation of the Yee-FDTD algorithm on elongated domains

A postprocessing method to compensate for the numerical dispersion of the Yee-FDTD scheme is presented. The method makes use of frequency domain deconvolution of the erroneous phase shift from the obtained results and can be applied on certain specific conditions, such as for simulations on elongated computational domains. Validation of the method is performed by comparing to analytical solution in a simplified empty-space scenario. Application to simulation of an UWB deflection sensing system is demonstrated, with good match between numerical and measured results.
