T-matrix representation of optical scattering response: Suggestion for a data format

Nigar Asadova, Karim Achouri, Kristian Arjas +39

The transition matrix, frequently abbreviated as T-matrix, contains the complete information in a linear approximation of how a spatially localized object scatters an incident fiel…

Local versus bulk circular dichroism enhancement by achiral all-dielectric nanoresonators

Krzysztof M. Czajkowski, Tomasz J. Antosiewicz

Large optical chirality in the vicinity of achiral high index dielectric nanostructures has been recently demonstrated as useful means of enhancing molecular circular dichroism. We…

SMUTHI: A python package for the simulation of light scattering by multiple particles near or between planar interfaces

Amos Egel, Krzysztof M. Czajkowski, Dominik Theobald +3

SMUTHI is a python package for the efficient and accurate simulation of electromagnetic scattering by one or multiple wavelength-scale objects in a planarly layered medium. The sof…

Polarization-dependent mode coupling in hyperbolic nanospheres

Krzysztof M. Czajkowski, Maria Bancerek, Alexander Korneluk +2

Hyperbolic materials offer a much wider freedom in designing optical properties of nanostructures than ones with isotropic and elliptical dispersion, both metallic or dielectric. H…

Far-field intensity signature of sub-wavelength microscopic objects

Maria Bancerek, Krzysztof M. Czajkowski, Rafal Kotynski

Information about microscopic objects with features smaller than the diffraction limit is almost entirely lost in a far-field diffraction image but could be partly recovered with d…

Multipole analysis of substrate-supported dielectric nanoresonator arrays with T-matrix method

Krzysztof M. Czajkowski, Maria Bancerek, Tomasz J. Antosiewicz

Substrates, and layered media in general, are ubiquitous, affect the properties of whatever is in their vicinity, and their influence is, in an arbitrary framework, challenging to…

Single-pixel imaging with sampling distributed over simplex vertices

Krzysztof M. Czajkowski, Anna Pastuszczak, Rafal Kotynski

We propose a method of reduction of experimental noise in single-pixel imaging by expressing the subsets of sampling patterns as linear combinations of vertices of a multidimension…

Surface-enhanced Raman scattering in graphene deposited on AlGaN/GaN axial heterostructure nanowires

Jakub Kierdaszuk, Mateusz Tokarczyk, Krzysztof M. Czajkowski +11

The surface-enhanced Raman scattering in graphene deposited on AlxGa1-xN/GaN axial heterostructure nanowires was investigated. The intensity of graphene Raman spectra was found not…

Real-time single-pixel video imaging with Fourier domain regularization

Krzysztof M. Czajkowski, Anna Pastuszczak, Rafal Kotynski

We present a closed-form image reconstruction method for single pixel imaging based on the generalized inverse of the measurement matrix. Its numerical cost scales linearly with th…

Single-pixel imaging with Morlet wavelet correlated random patterns

Krzysztof M. Czajkowski, Anna Pastuszczak, Rafał Kotyński

Single-pixel imaging is an indirect imaging technique which utilizes simplified optical hardware and advanced computational methods. It offers novel solutions for hyper-spectral im…
