Abstract

Multidomain pseudospectral time‐domain (MPSTD) algorithm, previously proposed for a Cartesian coordinates system, is extended to Maxwell's equations in a curvilinear coordinates system and applied to electromagnetic wave problems. A novelty patching technique is derived to effectively implement the boundary conditions at the interface between two adjacent subdomains by using characteristic variables. A perfectly matched layer (PML) in a curvilinear coordinates system is constructed according to a well‐posed PML in a Cartesian coordinates system. Numerical results are presented to illustrate the efficiency and accuracy of the method. Β© 2007 Wiley Periodicals, Inc.

In this paper a time fractional Fourier law is obtained from fractional calculus. According to the fractional Fourier law, a fractional heat conduction equation with a time fractional derivative in the general orthogonal curvilinear coordinate system is built. The fractional heat conduction equation
