Hybrid Longitudinal-Transverse Propagating Electric Fields in Photonic Crystal Waveguides
Yanrong Zhang, Hooman Barati Sedeh, Christopher S. Whittington +3
In a uniform, source-free, and unbounded medium, Maxwell's equations require electromagnetic waves to be purely transverse. However, when a beam of light is tightly focused or stro…
