Rayleigh plane wave expansion

Webinterpreted as an integral summation of plane waves propagating in all directions, including evanescent waves. It is the plane-wave expansion (including evanescent wave) of a spherical wave. Figure 35.2: The wave is propagating for k ˆvectors inside the disk, while the wave is evanes-cent for k ˆoutside the disk. WebFirst define the two representations of the plane wave: the simple exponential as 'pw' and the Bessel function expansion as 'pw_exp'. In [10]: # The plane wave def pw(x,y): return np.exp(1j*k0*x) In [11]: # The expansion of the plane wave def pw_exp(x,y,lmax): # sum over l ranges from -lmax to lmax z=x+1j*y # r=np.abs(z) th=np.angle(z) result=0 ...
