Frequency-dependent criticality in optical properties of the Drude metals, including plasmas and seawater

Bikram Keshari Behera, Rhitabrata Bhattacharyya, Shyamal Biswas

We have analytically determined attenuation constant, phase constant, and reflectivity of Drude metals over the entire frequency range ($0<\omega <\infty$) for an incident electromagneti…
