A neural operator-based surrogate solver for free-form electromagnetic inverse design
Yannick Augenstein, Taavi Repän, Carsten Rockstuhl
Neural operators have emerged as a powerful tool for solving partial differential equations in the context of scientific machine learning. Here, we implement and train a modified F…
Optical reconfiguration and polarization control in semi-continuous gold films close to the percolation threshold
Christian Frydendahl, Taavi Repän, Mathias Geisler +7
Controlling and confining light by exciting plasmons in resonant metallic nanostructures is an essential aspect of many new emerging optical technologies. Here we explore the possi…
Mid-infrared directional surface waves on a high aspect ratio nano-trench platform
Osamu Takayama, Evgeniy Shkondin, Andrey Bodganov +8
Optical surface waves, highly localized modes bound to the surface of media, enable manipulation of light at nanoscale, thus impacting a wide range of areas in nanoscience. By appl…
Dark-field hyperlens: Super-resolution imaging of weakly scattering objects
Taavi Repän, Andrei V. Lavrinenko, Sergei V. Zhukovsky
We propose and numerically demonstrate a technique for subwavelength imaging based on a metal-dielectric multilayer hyperlens designed in such a way that only the large-wavevector…
