04. Surface Coils - Impedance & Centred T/R Coils (SFCALC.EXE)

A download for SFCALC.EXE is available. To use it, download the SFCALC.EX_ file and rename it to SFCALC.EXE. This program will only run on PC computers with operating systems from MS-DOS to Windows XP. It does not run on PCs with Windows 7 operating system unless an MS-DOS emulator program like "DOS-Box" is installed.

All units are MKS.

SFCALC.EXE calculates the induced voltage in a single impedance coil or in a transmit-receive coil configuration where the transmit and receive coils have the coils have common centre axes. The program can calculate the influence of eddy current and magnetic field in two lower plates and one upper plate. The plates have finite thickness, but they are assumed to have infinite radial extent. The plate materials are assumed to be linear, homogeneous and isotropic with user defined electrical conductivity and relative magnetic permeability.

SFCALC.EXE can calculate solutions for up to 20 different configurations (problems) at a time. The program generates a ".dat" file with real and imaginary voltage components, and both real and imaginary components that have been normalized with respect to the coils in free space (ie. without the plates present). The program also generates a ".val" file with text information on the user input parameters defining the configurations that were solved.
