Journal of Nanophotonics • Open AccessEditorial: Vanishing methods
One of my graduate students decided to use a popular commercial software in order to investigate scattering by three-dimensional (3-D) objects. Within a few weeks, he came up with very nice plots of scattering patterns as well as colorful spatial profiles of scattered fields. As the 3-D objects were of complicated shapes and my brain is still wired to analytical treatments of scattering, I asked him to repeat his calculations for a sphere made of an isotropic material. After looking at the diagrams he supplied, I decided that something had gone wrong.
