How to set a self-consistent polarization direction of an obliquely incident laser?

[Bellahra]

Dear Epoch developers,

I am curious about if the electric field direction of an obliquely incident laser can be set as perpendicular to its wave vector but not the coordinate axes. That is, if I want to launch an obliquely incident laser on the x_min boundary, I have to give its pol_angle or pol to specify the polarization direction. However, the pol_angle (pol) is the angle clockwise about the coordinate axis but not the wave vector, but if so the electromagnetic wave is not a transverse wave any longer. So I want to know if is there any trick to set a self-consistent polarization of an obliquely incident laser. My Epoch version is 4.16.

If the laser is on x min then the default E field is in the y-direction and the B field is the z-direction. The polarisation angle is measured clockwise about the x-axis with zero along the Ey direction.

Thanks in advance.

Hey Bell,

Does our Injecting the laser at an angle demo provide the functionality you're after? You're right that the pol key only rotates the direction of E and B about the wave-vector, without rotating the wave-vector itself.

Hope this helps,
