Bringing Maxwell's equations to heel

Article Abstract:

Remcom's XFDTD version 5.0 electro-magnetic (EM) analysis software is distinguished from the competition by its efficient implementation of the finite-difference time-domain (FDTD) method, which uses memory efficiently and can be applied to many different problems. The new version supports all Microsoft Windows environments and benefits from a new user interface that relies more on menus to define and mesh geometrical structures, assign material properties and sources, execute FDTD calculations, and analyze results. XFDTD's data visualization functions have been enhanced with the ability to visualize 3D structures as they are created by panning or zooming through 2D slices or by generating complete 3D plots. Among its new technical features are implementation of current sources, thin wires and more advanced absorbing boundary conditions. Also added is the ability to calculate S-parameters defined at any port as a function of frequency. XFDTD 5.0 costs from $9,000.

Interactive, object-oriented Xmath

Article Abstract:

Integrated Systems Inc's $2,495 Xmath mathematical software package is a powerful interactive program that lets users perform numerical computations on Unix, VMS-based workstations and most X-Windows environments. Xmath, like other mathematical packages in its class, are based on efficient routines for matrix calculations. Such programs feature a programming language and built-in subroutines that ease the process of numerical computation. Outstanding features of the program include a friendly windows-based graphical user interface and the MathScript programming language. With MathScript, users define objects and operate on the objects with the more than 200-plus built-in user-defined or Xmath commands. Xmath also comes with a large library of functions and striking graphics capabilities. A more thorough tutorial would be welcomed.
