Improved Huygens’ Principle for Metamaterial

Crystals, 2023
In this paper, we propose a new method based on Huygens’ principle for calculations of transmission spectra with weak coupling and we call this method an improved Huygens’ principle.

Micromagnetic simulations of absoption spectra [PDF]

Journal of Magnetism and Magnetic Materials, 2006
Further development of a previously introduced method for numerically simulating magnetic spin waves is presented. Together with significant improvements in speed, the method now allows one to calculate the energy absorbed by the various modes excited by a position- and time-dependent H1 field in a ferromagnetic body of arbitrary shape in the presence ...

Effect of Protein Conformation and AMP Protonation State on Fireflies’ Bioluminescent Emission

Molecules, 2019
The emitted color in fireflies’ bioluminescent systems depends on the beetle species the system is extracted from and on different external factors (pH, temperature…) among others.

Fine-tuning ab initio XANES spectra calculations using the Bayesian optimization algorithm

Journal of Synchrotron Radiation
Theoretical modeling of X-ray absorption near-edge structure (XANES) spectra is often performed to interpret experimental spectra and to relate spectral features to the atomic and electronic structure of materials. The sensitivity of the XANES spectra to

Model Implementation of Lorentzian Spectra for Circuit Noise Simulations in the Frequency Domain

IEEE Journal of the Electron Devices Society, 2022
This work presents a new method for the Verilog-A implementation of Lorentzian noise models, in a module called VERILOR, which can automatically generate either Lorentzian or 1/f-like noise spectra depending on the trap density and gate oxide area, for ...

Three-dimensional simulations of turbulent spectra in the local interstellar medium [PDF]

Nonlinear Processes in Geophysics, 2007
Three-dimensional time dependent numerical simulations of compressible magnetohydrodynamic fluids describing super-Alfvénic, supersonic and strongly magnetized space and laboratory plasmas show a nonlinear relaxation towards a state of near ...

Approach for Preservation and Reconstruction of Two-Dimensional Wave Spectra and Its Application to Boundary Conditions in Nested Wave Modeling

Remote Sensing, 2023
Typically, storing a two-dimensional wave spectrum could occupy more than one thousand storage units, making saving and reading boundary spectra computationally burdensome in nested wave simulations. This paper proposes a new approach for preservation of

Witnessing eigenstates for quantum simulation of Hamiltonian spectra [PDF]

Science Advances, 2018
We introduce the concept of an eigenstate witness and use it to find energies of quantum systems with quantum computers.

Monte Carlo-based identification of electron and proton edges for calibration of miniaturized tissue equivalent proportional counter

Nuclear Engineering and Technology, 2023
Miniaturized tissue equivalent proportional counters (mini-TEPCs) are proper for radiation dosimetry in medical application because the small size of the dosimeter could prevent pile-up effect under the high intensity of therapeutic beam.
