DESCRIPTION

Function to analyze the self and mutual inductances of two parallel rectanglar bars.

EXAMPLE

 // Width of bar #1
a=10e-6;
 // Thickness of bar #1
b=1e-6;
 // Length of bar #1
l1=1e-3;
 // Width of bar #2
d=10e-6;
 // Thickness of bar #2
c=1e-6;
 // Length of bar #2
l2=1e-3;
 // Position of bar #2 in the width direction
E=12e-6;
 // Position of bar #2 in the thickness direction
P=0;
 // Position of bar #2 in the length direction
l3=0;
 // 1 GHz operation
