详 情 说 明

The Electromagnetic Finite-Difference Time-Domain (EmFDTD) tool kit is a powerful two-dimensional FDTD code that was developed by foreign experts at the School of Electrical Engineering, Sharif University of Technology. This code, which is based on the standard Yee's FDTD algorithm, provides a range of applications including propagation, scattering, and diffraction of electromagnetic waves in homogeneous and non-homogeneous isotropic media for in-plane propagating waves. It is important to note that negative permittivities or permeabilities as well as dispersion are not included in the code. However, it does allow for the selective application of zero, periodic, and perfectly matched layer boundary conditions to the solution domain.

The EmFDTD program is best suited for the study of propagation and diffraction of electromagnetic waves in photonic crystal structures. It is written in the MATLAB programming language and has been extensively tested under MATLAB 5.0 and higher versions. With its wide range of applications and its ease of use, the EmFDTD tool kit is an excellent resource for researchers and engineers who are interested in the study of electromagnetic waves in a variety of materials and structures.
