However, the breaking of waves is delayed when the value of the Tsallis q parameter and the Tsallis temperature T are higher.doi:10.1140/epjc/s10052-020-8191-4Trambak BhattacharyyaAbhik MukherjeeSpringer Berlin HeidelbergThe European Physical Journal C...
The wave propagation in a simply supported travelling beam, studied in Part I of this paper, has been used to derive the forced responses. Based upon the wave-propagation principles, a simple method for constructing the closed-form transfer function of such a beam has been presented. The use...
Making use of the continuity conditions of the physical quantities across the interface, the global propagator relation is assembled by propagating the solutions in each layer from the bottom to the top of the layered plate. From the global propagator matrix, the dispersion equation is obtained by...
Therefore, the existence of the asymmetric modes at all frequencies leads to an extremely large level of nonreciprocal transmission over a very large range of frequencies, a performance that is unprecedented among wave-based physical systems. Since the nonreciprocal transmission is broadband, our ...
The aim of the investigation is to simulate the interaction of an ion Bernstein wave (IBW) with a collisionless plasma. The problem is dealt with in the frame of a one‐dimensional slab model, where all physical quantities vary in the direction of wave propagation. Electrons constitute a ...

Signal waveform is the basic physical layer element that fundamentally determines the most important key performance indicator in communication systems, namely spectral efficiency. Traditional waveforms rely on orthogonal Nyquist shaping but result in restricted spectral efficiency. Non-orthogonal waveforms have...
