Inverse designed full-Stokes polarimetric metasurface with simultaneous wavefront sensing for visible light
OndÅej Äervinka, Martin HrtoÅ, Å tÄpán Venos +4
Metasurfaces have emerged as a powerful platform for compact optical sensors by replacing bulky lenses with flat arrays of subwavelength nanostructures. In precision optical metrol…
Optimal conditions for detecting optical dichroism at the nanoscale by electron energy-loss spectroscopy
Marek Zálešák, Martin Ošmera, Martin HrtoŠ+1
The emergence of optical circular dichroism in chiral nanoscale and molecular systems provides not only a way for analyzing the sample chirality itself but also additional degrees…
SpinWaveToolkit: Python package for (semi-)analytical calculations in the field of spin-wave physics
Jan KlÃma, OndÅej Wojewoda, Jakub KrÄma +4
We present an open-source Python package, SpinWaveToolkit (SWT), for (semi-)analytical modeling of spin-wave dynamics in thin ferromagnetic films and exchange-coupled magnetic bila…
Establishing a library of metasurface building blocks through coherence-controlled holographic microscopy
OndÅej Äervinka, Vlastimil Weiss, Martin HrtoÅ +5
Digital holographic microscopy is a powerful tool for characterizing transparent and reflective phase objects. Its ability to reconstruct amplitude and phase can also offer great i…
Modeling of the micro-focused Brillouin light scattering spectra
OndÅej Wojewoda, Martin HrtoÅ, Michal Urbánek
Although micro-focused Brillouin light scattering (BLS) has been used for more than twenty years, it lacks a complete theoretical description. This complicates the analysis of expe…
