Pu Zhang

In RF module probably you can do that with the scattered field formulation.

Mahendar Kumbham

Hi Pu,

scattered field formulation is preferred in homogeneous medium. I need to model in substrate-air layer. All LG equations are in radial and azimuth coordinates which I can't use in Cartesian 3D model.

Thanks for reply

Mahendar
