Fast estimation of propagation constants in crossed gratings
Ehsan Faghihifar, Mahmood Akbari, Seyed Amir Hossein Nekuee
Fourier-based modal methods are among the most effective numerical tools for the accurate analysis of crossed gratings. However, leading to computationally expensive eigenvalue equ…
Exclusive robustness of Gegenbauer method to truncated convolution errors
Ehsan Faghihifar, Mahmood Akbari
Spectral reconstructions provide rigorous means to remove the Gibbs phenomenon and accelerate the convergence of spectral solutions in non-smooth differential equations. In this pa…
Propagation of Light in Photonic Crystal Fibre Devices
Ali Dabirian, Mahmood Akbari, Niels Asger Mortensen
We describe a semi-analytical approach for three-dimensional analysis of photonic crystal fibre devices. The approach relies on modal transmission-line theory. We offer two example…
The radiated fields of the fundamental mode of photonic crystal fibers
Ali Dabirian, Mahmood Akbari, Niels Asger Mortensen
The six-fold rotational symmetry of photonic crystal fibers has important manifestations in the radiated fields in terms of i) a focusing phenomena at a finite distance from the en…
