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.

 

 

Supported Product: FDTD, MODE

 

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);
