Calculates the integral of the far field projection over some range of theta in 2D simulation. Angles are specified in degrees, but the integral is done in radians.
$$ \int_{\theta} E^{2}(\theta) d \theta $$
Syntax 
Description 

out = farfield2dintegrate(E2, theta, halfangle, theta0); 
Integrate 2D far field projection data. 
Parameter 
Default value 
Type 
Description 


E2 
required 
matrix 
E field data from farfield2d 

theta 
required 
matrix 
Theta from farfieldangle 

halfangle 
optional 
90 
vector 
Half angle (in degrees) of the integration region. Must have same length as theta0 or length 1. Half angle should be between 0 to 90 degrees. 
theta0 
optional 
0 
vector 
Center angle (in degrees) theta of the integration region. Must have same length as halfangle or length 1. Theta0 should be between 90 to 90 degrees. 
Example
Calculate the fraction of power in the far field from 20 to 70 degrees.
m="monitor1"; E2=farfield2d(m); theta=farfieldangle(m); ?farfield2dintegrate(E2,theta,25,45) / farfield2dintegrate(E2,theta);
