For example, I set the E0 vector to (0,0,1) ,k vector is (-1,0,0), but I want to directly set the incident wave to theta=90 degree, phi=0~180 degrees to do an angle range scan directly. How can I set it? Or I only can slowly set it from phi=0, phi=1...phi=180?
Equation (2) requires a large number of Bloch wavefunctions to converge. Moreover, they all scale cubically with respect to the number of atoms in the system (Methods), which limits their scope of applications. In fact, we can leverage locality in real space to considerably speed up the ...

one of the two circular polarization states has a plane wavefront (i.e., zero orbital angular momentum). For a dark C-point singularity, both the circular polarization states carry nonzero and unequal orbital angular momentum. For our study, we only consider bright C-points as they are easi...

Conical Projection in planeAssuming that you are trying to visualize a cone that emanates from a point and extends outward into 2D or 3D space the "fill" and "plot" functions for the 2D space and the "fill3" and "plot3" functions for the 3D space can be used to visualize the ...
A wave is a disturbance passing through a medium. The wave carries energy and momentum with it. As an example of a wave assume there are some bricks arranged in a line as shown in Fig. 7.1a. Suppose we push one of the bricks at one of the end, then the bricks fall in sequence, ...
