Rcwa normal vector

WebIn order to obtain the reciprocal lattice vectors, one has to define the incident wavelength and real space unit cell size and scale the grid by these. This RCWA implementation works for arbitrary plane wave incidence conditions. However, $\theta$ should not be set to zero in order to avoid numerical singularities. WebAug 18, 2014 · Pabs=-0.5real (div.vec_P). It is possible to calculate the absorption directly from this formula (see the Divergence of Poynting vector section), but divergence calculations tend to be very sensitive to numerical problems. Fortunately, there is a more numerically stable form. It can be shown that the above formula is equivalent to.
