function q = fresnel_op1_rectTM_cent(X1,X2,varargin)

qValue = 0.5 + 1i*1E6; % perfectly conducting, so imaginary part is infinity...
% real part from reconstruction... not sure if correct...

w = 12.7E-3; % width = 12.7 mm
h = 24.5E-3; % height = 24.5 mm

right = 0; % move it right
up    = -3E-3; % move it up (or down with a negative number)
% shift the target 3 mm down... and it does visual better fit to Fresnel data

q = (-w/2+right <= X1) & (X1 <= w/2+right) & (-h/2+up <= X2) & (X2 <= h/2+up);
q = qValue*q;
q = double(q);
