Abstract: The advent of transformation optics and metamaterials has made possible devices producing extreme effects on wave propagation. Here we give theoretical designs for devices, Schr\"odinger hat...
Analogy of the grounded conducting sphere image problem with mirror optics
Analogy sphere image problem mirror optics
<
2011/8/5
Abstract: We show that in the grounded conducting sphere image problem, all the necessary information about the image charge can be found from a mirror equation and a magnification formula. Then, we p...
