چکیده

Time-varying media have recently emerged as a new paradigm for wave manipulation, due to the synergy between discovery of highly nonlinear materials, such epsilon-near-zero and quest applications, magnet-free nonreciprocity, multimode light shaping, ultrafast switching. In this review, we provide comprehensive discussion recent progress achieved with photonic metamaterials whose properties stem from their modulation in time. We review basic concepts underpinning temporal switching its relation spatial scattering deploy resulting insight time-crystals emergent research avenues, topological non-Hermitian physics. then extend our account spatiotemporal applications synthetic motion, giant anisotropy, amplification, many other effects. Finally, conclude most attractive experimental avenues demonstrated few perspectives on emerging trends future implementations time-modulation photonics.

FINITE-TIME PASSIVITY OF DISCRETE-TIME T-S FUZZY NEURAL NETWORKS WITH TIME-VARYING DELAYS

This paper focuses on the problem of finite-time boundedness and finite-time passivity of discrete-time T-S fuzzy neural networks with time-varying delays. A suitable Lyapunov--Krasovskii functional(LKF) is established to derive sufficient condition for finite-time passivity of discrete-time T-S fuzzy neural networks. The dynamical system is transformed into a T-S fuzzy model with uncertain par...

Finite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay

In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...

Time Dependent Analysis of Micro-tubes Conveying Nanofluids Under Time-Varying Heat Flux

  In this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. In this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. It is observed that the pumping power of nanofluid flowing and the maximum temperatur...

Approximation Solutions for Time-Varying Shortest Path Problem

Abstract. Time-varying network optimization problems have tradition-ally been solved by specialized algorithms. These algorithms have NP-complement time complexity. This paper considers the time-varying short-est path problem, in which can be optimally solved in O(T(m + n)) time,where T is a given integer. For this problem with arbitrary waiting times,we propose an approximation algorithm, whic...
