Abstract
In this research we explore the possibility to implement an optical target that eliminates incoming wave in finite-different time-domain (FDTD) simulations. This is achieved by a modified morphology of an absorbing boundary condition (ABC). In particular, our model is based on convolutional perfectly matched layers (CPML) ABC. To validate this method, a cylindrical CPML region is constructed as artificial absorbing material and simulated using a two-dimensional FDTD algorithm. Its performance is analyzed for focused beam wave source conditions. Varying the spatial size of the circular CPML, we compute the absorption efficiency for a wide range of applications and demonstrate its performance as a numerical optical target in FDTD simulations. We demonstrate that the reported simulation construct can effectively eliminate impinging light wave for a macroscopic light scattering simulation.
