Superdimensional Metamaterial Resonators
Allan Greenleaf, Henrik Kettunen, Yaroslav Kurylev +2
We propose a fundamentally new method for the design of metamaterial arrays, valid for any waves modeled by the Helmholtz equation, including scalar optics and acoustics. The desig…
On Absence and Existence of the Anomalous Localized Resonance without the Quasi-static Approximation
Henrik Kettunen, Matti Lassas, Petri Ola
The paper considers the transmission problems for Helmholtz equation with bodies that have negative material parameters. Such material parameters are used to model metals on optica…
Cloaking and Magnifying Using Radial Anisotropy
Henrik Kettunen, Henrik Wallén, Ari Sihvola
This paper studies the electrostatic responses of a polarly radially anisotropic cylinder and a spherically radially anisotropic sphere. For both geometries, the permittivity compo…
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…
