How to launch two plane wave sources in wave optics module?

Please login with a confirmed email address before reporting spam

Suppose I want to simulate the E-field in layered medium (e.g. glass-gold-air in Kretschmann configuration for SPP), I normally add two ports, one with excitation on. If I want to launch two counter-propagating sources to form a standing wave, then in addition to adding an extra port (port 3 with excitation on, and angle = -alpha), are there any other better methods?
