Observation of Asymmetric Transport in Structures with Active Nonlinearities

Observation of asymmetric transport in structures with active nonlinearities.

A mechanism for asymmetric transport which is based on parity-time-symmetric nonlinearities is presented. We show that in contrast to the case of conservative nonlinearities, an increase of the complementary conductance strength leads to a simultaneous increase of asymmetry and transmittance intensity. We experimentally demonstrate the phenomenon using a pair of coupled Van der Pol oscillators ...

Dirichlet Problems with Asymmetric Nonlinearities

Asymmetric Light Propagation in Active Photonic Structures

This thesis will present a theoretical and numerical analysis of optical systems exhibiting non-reciprocity, with potential applications in the field of integrated opto-electronic circuits. We will carefully engineer structures with highly-asymmetric transport properties, where traits such as reflectance and transmittance are dependent upon the incident direction of the interrogating waves. Thi...

investigation in performance level of asymmetric structures

according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...

Active patterning and asymmetric transport in a model actomyosin network.

Cytoskeletal networks, which are essentially motor-filament assemblies, play a major role in many developmental processes involving structural remodeling and shape changes. These are achieved by nonequilibrium self-organization processes that generate functional patterns and drive intracellular transport. We construct a minimal physical model that incorporates the coupling between nonlinear ela...
