Here, we outline a simple yet powerful design principle to perceive a nanoantenna that provides directional scattering into a higher index substrate based on the interference of multiple electric dipoles. A structural implementation of the electric dipole distribution is possible using plasmonic nanoparticles with a fairly simple geometry, i.e. two coupled rectangular nanoparticles, forming a dimer, on top of a substrate. The key to achieve directionality is to choose a sufficiently large size for the nanoparticles. This promotes the excitation of vertical electric dipole moments due to the bi-anisotropy of the nanoantenna. In turn, asymmetric scattering is obtained by ensuring the appropriate phase relation between the vertical electric dipole moments. The scattering strength and angular spread for an optimized nanoantenna can be shown to be broadband and robust against changes in the incidence angle. The scattering directionality is maintained even for an array configuration of the dimer. It only requires the preferred scattering direction of the isolated nanoantenna not to be prohibited by interference.}, language = {en} } @article{GregersendeLassonFrandsenetal.2018, author = {Gregersen, Niels and de Lasson, Jakob Rosenkrantz and Frandsen, Lars Hagedorn and Gutsche, Philipp and Burger, Sven and Kim, Oleksiy S. and Breinbjerg, Olav and Ivinskaya, Aliaksandra and Wang, Fengwen and Sigmund, Ole and H{\"a}yrynen, Teppo and Lavrinenko, Andrei}, title = {Benchmarking state-of-the-art numerical simulation techniques for analyzing large photonic crystal membrane line defect cavities}, volume = {10672}, journal = {Proc.

This time-even pseudoscalar has been dismissed as being a higher-order version of helicity. Nevertheless, we revisit the derivation of the underlying conservation law and define optical chirality in media similar to. We identify the mechanism of chirality conversion by either inhomogeneous or anisotropic space to complement the conservation of optical chirality. The conservation law of optical chirality in arbitrary space enables the extension of the concept of polarization to the near-field where no distiniguished propagation direction of light is present. We show that the connection of electromagnetic energy and optical chirality provide the ability to define a circular polarization basis in time-harmonic near-field analysis. In order to illustrate our theory, we present electromagnetic field simulations of simple as well as more complex nanostructures. Results using the well-known far-field polarization concept are readily reproduced and extended from the point of view of chirality conversion.}, language = {en} } @inproceedings{GregersendeLassonFrandsenetal.2017, author = {Gregersen, Niels and de Lasson, Jakob Rosenkrantz and Frandsen, Lars Hagedorn and Kim, Oleksiy S. and Breinbjerg, Olav and Wang, Fengwen and Sigmund, Ole and Ivinskaya, Aliaksandra and Lavrinenko, Andrei and Gutsche, Philipp and Burger, Sven and H{\"a}yrynen, Teppo and Merk, Jesper}, title = {Comparison of five numerical methods for computing quality factors and resonance wavelengths in photonic crystal membrane cavities}, booktitle = {CLEO/Europe-EQEC}, doi = {10.1109/CLEOE-EQEC.2017.8087750}, year = {2017}, language = {en} }
