Numerical examples demonstrate the efficiency and practicality of our algorithm. These function types in the discrete-time convolution allow for their substitution by memory variables, annihilating the otherwise prohibitive computing demands. Key components to our solution for highly digitized model meshes are Debye decomposition and composite memory variables.
FDTD SOLUTION SOFTWARE
Its inversely Laplace-transformed Debye decomposition results in a series of time convolutions between electric field and exponential decay functions, with the latter reflecting each Debye constituents’ individual relaxation time. Descriptions: FDTD Solutions is a powerful and comprehensive software for designing, analyzing and optimizing electromagnetic devices, integrated circuits, medical devices and optoelectronic, photonic and nanophotonic products in a three-dimensional and fully graphical environment. We revert to the popular Cole–Cole model of dispersion to describe the frequency-dependent behaviour of electrical conductivity. Key components to our solution for highly digitized model meshes are Debye decomposition and composite memory variables. Compared to the non-dispersive problem, the discrete dispersive Maxwell system contains costly convolution operators. The finite-difference time-domain (FDTD) method has been widely used for the numerical analysis of transient electromagnetic problems because it is. Numerical results show high efficiency and accuracy of the proposed method.The finite-difference time-domain scheme is augmented in order to treat the modelling of transient electromagnetic signals containing induced polarization effects from 3-D distributions of polarizable media. In addition, because US-FDTD is only used in one of the subdomains, compared with global US-FDTD method, the matrix dimension of hybrid FDTD is reduced, which saves the time for eigenvalue solution. Hybrid FDTD makes the explicit time marching with a uniform time step determined by the size of coarse grid in whole domain, which reduces the iteration time.
