%STRIP
%   Creates a dipole antenna (thin strip) in the xy-plane
%
%   The following parameters need to be specified:
%   Strip width (along the x-axis)          W
%   Strip length (along the y-axis)         L
%   Discretization parameter (width)        Nx
%   Discretization parameter (length)       Ny
%
%   Note: the equivalent wire radius is 0.25*W
%
%   For more general version of this script please 
%   see strip_.m of Appendix A.
