CAD in light optics and electron optics

In 1854 J. C. Maxwell devised his fish-eye lens a sphere with a radially diminishing refractive index [*1. The optical characteristics of this lens, which can produce aperfect image of an object, as the computer plot above suggests, are fairly easy to calculate analytically. This is not generally the case with optical elements of varying refractive index as used today for data transmission. The...

Electron optics in graphene

In ballistic graphene, electrons behave in many ways similar to photons. By changing the electrostatic potential locally, we realized elements in graphene that are known from optics. But in contrast to conventional optics, gapless p-n interfaces can be formed showing a negative index of refraction and the effect of Klein tunneling. Even more, electron trajectories can be bent by applying a magn...
