A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators
Laser &Photonics Reviews, EarlyView.ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.

Energy-stable port-Hamiltonian systems
Applied Mathematics LettersWe combine energy-stable and port-Hamiltonian (pH) systems to obtain energy-stable port-Hamiltonian (espH) systems. The idea is to extend the known energy-stable systems with an input-output port, which results in a pH formulation. One advantage of the new espH formulation is that it naturally preserves its espH structure throughout discretization (in ...

Laser &Photonics Reviews, EarlyView.An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.

Energy-based Hamiltonian approach in H∞ controller design for n-degree of freedom mechanical systems
Systems Science & Control Engineering, 2019 This paper studies the energy-based approach for ${H_\infty } $ controller design of $n $-degree of freedom mechanical systems. In this approach, the Hamiltonian function, which is the sum of kinetic and potential energies of the system, is considered as

Modelling car-following dynamics with stochastic input-state-output port-Hamiltonian systems [PDF]
EPJ Web of ConferencesIn this contribution, we introduce a general class of car-following models with an input-state-output port-Hamiltonian structure. We derive stability conditions and long-term behavior of the finite system with periodic boundaries and quadratic ...

Bounded Frequency Lattices in Coupled Lithium Niobate Ring Cavities
Laser &Photonics Reviews, EarlyView.We leverage coupled asymmetric ring resonators in realizing bounded tight‐binding frequency lattices and demonstrate their discrete band structures on an integrated device. Suppression of long‐range coupling with a single auxiliary cavity is demonstrated by combining mode splitting and coupled waveguide dispersion effects.

Neural network quaternion-based controller for port-Hamiltonian system
Demonstratio MathematicaIn this research article, a control approach for port-Hamiltonian PH systems based in a neural network (NN) quaternion-based control strategy is presented. First, the dynamics is converted by the implementation of a Poisson bracket in order to facilitate
