Transformation Acoustics in Generic Elastic Media
Luzi Bergamin
In this work a transformation acoustics scheme for generic elastic media is developed. Our approach starts form the decomposition of the elasticity tensor in terms of its eigentens…
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…
Realization of the D'B' boundary condition
I. V. Lindell, A. Sihvola, L. bergamin +1
In this paper we find a realization for the D'B'-boundary conditions, which imposes vanishing normal derivatives of the normal components of the D and B fields. The implementation…
Decomposable medium conditions in four-dimensional representation
Ismo V. Lindell, Luzi Bergamin, Alberto Favaro
The well-known TE/TM decomposition of time-harmonic electromagnetic fields in uniaxial anisotropic media is generalized in terms of four-dimensional differential-form formalism by…
The non-birefringent limit of all linear, skewonless media and its unique light-cone structure
Alberto Favaro, Luzi Bergamin
Based on a recent work by Schuller et al., a geometric representation of all skewonless, non-birefringent, linear media is obtained. The derived constitutive law is based on a "cor…
Negative index of refraction, perfect lenses and transformation optics -- some words of caution
Luzi Bergamin, Alberto Favaro
In this paper we show that a negative index of refraction is not a direct implication of transformation optics with orientation-reversing diffeomorphisms. Rather a negative index a…
