On the Minimal Scattering Response of PEC Cylinders in a Dielectric Cloak
Constantinos A. Valagiannopoulos, Pekka Alitalo, Sergei A. Tretyakov
Recently, it was shown that an infinite perfectly conducting (PEC) cylinder can be nearly perfectly cloaked from normally incident electromagnetic waves using a single-layer homoge…
Electromagnetic cloaking of cylindrical objects by multilayer or uniform dielectric claddings
Constantinos A. Valagiannopoulos, Pekka Alitalo
We show that dielectric or even perfectly conducting cylinders can be cloaked by a uniform or a layered dielectric cladding, without the need of any exotic or magnetic material par…
Experimental characterization of a broadband transmission-line cloak in free space
Pekka Alitalo, Ali E. Culhaoglu, Andrey V. Osipov +3
The cloaking efficiency of a finite-size cylindrical transmission-line cloak operating in the X-band is verified with bistatic free space measurements. The cloak is designed and op…
Bistatic scattering characterization of a three-dimensional broadband cloaking structure
Pekka Alitalo, Ali E. Culhaoglu, Andrey V. Osipov +3
Here we present the results of full experimental characterization of broadband cloaking of a finite-sized metallic cylinder at X-band. The cloaking effect is characterized by measu…
Nonlinear transformation optics and engineering of the Kerr effect
Luzi Bergamin, Pekka Alitalo, Sergei Tretyakov
The concept of transformation optics is extended to nonlinear electrodynamics. It is shown that transformation optics favors implicit constitutive relations in terms of energy dens…
Cloaking a metal object from an electromagnetic pulse: A comparison between various cloaking techniques
Pekka Alitalo, Henrik Kettunen, Sergei Tretyakov
Electromagnetic cloaks are devices that can be used to reduce the total scattering cross section of various objects. An ideal cloak removes all scattering from an object and thus m…
