Far Field Pattern Calculation

Hi Ynathan

The farfield does not have a specific absolute distance at which it is calculated. The 1/r distance dependency is removed in the field calculation to obtain the far field.

The distance at which the 1/r dependency is zero (or negligible) will of course depend on the model.

To calculate the fields at a specific distance, just request a near field at a large distance from the model. This would then essentially also be a 'far field', but then at a specific distance 

If the r component of the near field is very very small, then that specific distance could be seen as being 'in the far field' of the model.

How can choose theta and phi ranges for far field pattern? Is it specific to each problem?How can I identify the ranges to a particular problem?

Thanks in advance.

hi mgmv7

Not sure what you mean? The user must request the ranges of angles for the far field to calculate. This is on the Request far fields dialog.
