Large Element Physical Optics (LE-PO)

The large element physical optics (LE-PO) solution method is similar to the PO method but allows larger elements to be used.

The large element physical optics (LE-PO) is formulated for use in instances where electrically very large structures are modelled. This method should only be used when there are no discontinuities in the incident field (the field incident on the LE-PO face should closely represent a plane wave). LE-PO is similar to PO in that it is an asymptotic high-frequency numerical method of the same nature as the UTD.

The high-frequency large element physical optics method is applicable for large smooth areas when calculating near and far fields.
