gprMax is open source software that simulates electromagnetic wave propagation. It uses Yee's algorithm to solve Maxwell’s equations in 3D using the Finite-Difference Time-Domain (FDTD) method.
Study on discrete conical emission in MMFs with use of two well-known numerical approaches of nonlinear pulse propagation, namely, the unidirectional pulse propagation equation and the multimode generalized nonlinear Schrodinger equation.
Counting bacterial colonies is a fundamental task in microbiology. Currently, manual counting remains the gold standard. This is a timeconsuming and error-prone process, which requires a trained professional. To avoid these issues, the automated method can be applied for the task. The goal of our work was to design a model that counts and classifies bacterial colonies in Petri dishes using RGB images.
The field distribution of the same mode could be slightly different depending on wavelength and reflective index profile. To exhibit a dispersion characteristic for multimode fibers over a wide spectral range, a verification of refractive index value for a particular mode at a specific wavelength is needed.
There is an urgent need of clarifying the potential and areas of applicability of numerical models to facilitate the accurate design of future nonlinear and multimode fiber devices. Therefore we performed the simulations of conical emission using two well-known numerical tools, namely, the unidirectional pulse propagation equation and the multimode generalized nonlinear Schrodinger equation.
