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.
$$ \int_{\theta} E^{2}(\theta) d \theta $$

|
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);
