Optical Force and Torque on Dipolar Dual Chiral Particles
Aso Rahimzadegan, Martin Fruhnert, Rasoul Alaee +2
On the one hand, electromagnetic dual particles preserve the helicity of light upon interaction. On the other hand, chiral particles respond differently to light of opposite helici…
Dual and chiral objects for optical activity in general scattering directions
Ivan Fernandez-Corbaton, Martin Fruhnert, Carsten Rockstuhl
Optically active artificial structures have attracted tremendous research attention. Such structures must meet two requirements: Lack of spatial inversion symmetries and, a conditi…
Towards negative index self-assembled metamaterials
Martin Fruhnert, Stefan Mühlig, Falk Lederer +1
We investigate the magnetic response of meta-atoms that can be fabricated by a bottom-up technique. Usually such meta-atoms consist of a dielectric core surrounded by a large numbe…
Tunable scattering cancellation cloak with plasmonic ellipsoids in the visible
Martin Fruhnert, Alessio Monti, Ivan Fernandez-Corbaton +4
The scattering cancellation technique is a powerful tool to reduce the scattered field from electrically small objects in a specific frequency window. The technique relies on cover…
Objects of maximum electromagnetic chirality
Ivan Fernandez-Corbaton, Martin Fruhnert, Carten Rockstuhl
We introduce a definition of the electromagnetic chirality of an object and show that it has an upper bound. Reciprocal objects attain the upper bound if and only if they are trans…
