Generalized continuum models for analysis of one-dimensional shear deformations in a structural interface with micro-rotations
Aleksey A. Vasiliev, Andrey E. Miroshnichenko, Sergey V. Dmitriev
Generalized continuum models for describing one-dimensional shear deformations of a Cosserat lattice are considered and their application to describing of structural effects essent…
A discrete model and analysis of one dimensional deformations in a structural interface with micro-rotations
Aleksey A. Vasiliev, Andrey E. Miroshnichenko, Massimo Ruzzene
The static and dynamic properties of a Cosserat-type lattice interface of finite thickness are studied, so that both displacements and rotational degrees of freedom are taken into…
Fano resonances in nanoscale structures
Andrey E. Miroshnichenko, Sergej Flach, Yuri S. Kivshar
Nowadays nanotechnology allows to scale-down various important devices (sensors, chips, fibres, etc), and, thus, opens up new horizon for their applications. Nevertheless, the effi…
Sharp bends in photonic crystal waveguides as nonlinear Fano resonators
Andrey E. Miroshnichenko, Yuri S. Kivshar
We demonstrate that high transmission through sharp bends in photonic crystal waveguides can be described by a simple model of the Fano resonance where the waveguide bend plays a r…
Multi-field modelling of Cosserat solids
A. A. Vasiliev, A. E. Miroshnichenko
We construct multi-field generalisations of the Cosserat continuum model on the basis of the square lattice model that takes into account rotational degree of freedom of microstruc…
