The full-vector Maxwell's equations Unite-difference time-domain (FDTD) method is employed to calculate diffraction coefficients of vibrating conducting and dielectric wedges. Two-dimensional FDTD models of right-angle wedges are constructed to include total-field scattered-field incident plane-wave source conditions as well as convolutional perfectly matched-layer boundary conditions. These models are first validated by calculating the diffraction coefficient of a stationary perfect electrical conducting (PEC) right-angle wedge for comparison to uniform geometrical theory of diffraction (UTD) analytical solutions. Next, a brute-force FDTD technique for modeling wedge vibrations is utilized to calculate the Doppler diffraction coefficients of vibrating lossless and lossy
