摘要
A cloaking device comprised of a metallic cloaked region and a radially inhomogeneous cladding, obeying to a power law, is analyzed. Semi-analytical approximations are performed and simple formulas of the coating%26apos;s optimal material profile are derived, based on the structure%26apos;s miniature size. The variations of the coating%26apos;s permittivities with respect to the operating frequency and the physical dimensions of the structure are shown and discussed.
