%	semipolar(theta,rho,rmin,rmax,rticks,line_style,color) 
%************************************************************************
%	SEMIPOLAR is a function that plots patterns in polar coordinates
%	where THETA, in degrees, varies between 0 and 90 degrees.
%	RHO, in dB,  may be negative.
%
%	Input Parameters Description
%	----------------------------
%	- theta (in degrees) must be a row vector from 0 to 90 degrees
%	- rho (in dB) must be a row vector
%	- rmin (in dB) sets the minimum limit of the plot (e.g., -40 dB)
%	- rmax (in dB) sets the maximum limit of the plot (e.g.,   0 dB)
%	- rticks is the # of radial ticks (or circles) desired. (e.g., 4)
%	- linestyle is solid (e.g., '-' or dashed (e.g., '--')
