FDTD three-dimensional CPML

详 情 说 明

The Finite-Difference Time-Domain (FDTD) method is a numerical technique used to solve electromagnetic problems. It is particularly useful for simulating wave propagation in three-dimensional environments. One of the challenges of using the FDTD method is dealing with boundary reflections. This is where the Convolutional Perfectly Matched Layer (CPML) comes in. CPML is a technique used to absorb wave reflections at the boundaries of a simulation domain, thus allowing for more accurate results. Overall, the combination of FDTD and CPML has proven to be a powerful tool in the field of electromagnetic simulation.
