Is there a simple way to cut out the first quarter from a polar plot?
I am only interested in the region from 0 to pi/2; the rest is just
taking up space. How can I crop the plot to this quarter?

Example plot:

a=0:.1:pi/2;
polar(a,sin(2*a))

xl = get(gca,'XLim'); yl = get(gca,'YLim');
set(gca,'XLim', [0 xl(2)], 'YLim', [0 yl(2)]);

That was easier than I expected!

How about:

axis([0 inf 0 inf])
