Physical Optics (PO) and Large Element Physical Optics (LE-PO)

The physical optics (PO) solver method is an asymptotic high-frequency numerical method based on currents. Use the method in instances where electrically very large metallic or dielectric structures are modelled.

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