Singular value decomposition to describe bound states in the continuum in periodic metasurfaces
Nikita Ustimenko, Ivan Fernandez-Corbaton, Carsten Rockstuhl
Understanding how bound states in the continuum (BICs) emerge in periodic metasurfaces is essential for the controlled design of high-Q resonances and their systematic manipulation…
A Framework for Formulating Polychromatic Theories of Emission
Ivan Fernandez-Corbaton, Maxim Vavilin, Markus Nyman
The emission of energy as electromagnetic radiation is ubiquitous, in particular because objects release thermal energy in the form of photons. Most theories of thermal radiation a…
A Novel Chiroptical Spectroscopy Technique
Jorge Olmos Trigo, Cristina Sanz-Fernández, Ivan Fernandez-Corbaton
Chiral objects typically exhibit a different extinction for the two circular polarizations of light. Researchers often detect the chirality of objects by measuring this extinction…
Unified Evolution of Electromagnetic Sources in Homogeneous Fields
Ivanina Ilieva, Carsten Rockstuhl, Ivan Fernandez-Corbaton
In this work, we study the behavior of elementary electromagnetic sources, i.e., point-like electric charges and intrinsic magnetic dipoles, in the presence of homogeneous electrom…
Efficient computation of thermal radiation from biperiodic layered systems using the T-matrix method
Martin Gabbert, Markus Nyman, Lukas Rebholz +2
Metasurfaces are becoming important tools for the control of thermal radiation. Understanding their functional possibilities on computational grounds requires evaluating the respon…
Chiral cavities made from lattices of highly electromagnetically-chiral scatterers
Lukas Rebholz, Carsten Rockstuhl, Ivan Fernandez-Corbaton
The infamous weakness of molecular chiroptical responses challenges the all-optical realization of crucial applications such as enantio-selective sorting of chiral molecules, or bi…
