I am having trouble in writing a script to create a circular window function to find power at a certain plane got using farfieldexact3d. I want the power only at the window. Please help me with some code snippet.

Once you have say (x,y), you can first create 2D matrix:

X=meshgridx(x,y);

Y=meshgridy(x,y);

then create a circle:

window=ones(length(x),length(y))&((X^2+Y^2)<=RR^2);

image(x,y,window);

with given radius RR.

Please try.
