Call: ELECTRIC_FIELD_3

coordinates

This procedure accepts input arguments of types Number and Matrix.

If at least one of the input arguments x, y, z is of type Matrix, then all output arguments are of type Matrix, with the dimensions of the first input argument of type Matrix. If one or more input arguments are of type Number and one or more others of type Matrix, then the Number type arguments are "expanded" to become Matrices filled uniformly with the value of the Numbers.

The coordinates system expected by ELECTRIC_FIELD_3 is the internal frame. If you describe your cell in Cartesian coordinates, then the internal frame is simply the Cartesian coordinate system. If polar coordinates are used however, then you should supply the following parameters:

for x: log(r)
for y: \&phi;, in radians
for z: z

The z-coordinate is not affected by any of the conformal mappings currently in use by the program.

These mappings can be performed with the POLAR_TO_INTERNAL procedure.

field

The field is returned in internal coordinates. The internal coordinates system is Cartesian when the cell is described in Cartesian coordinates, but when you describe the cell in polar coordinates, you've to apply the following mapping:

Er = Ex/r
Ephi = Ey/r
Ez is invariant
