“…Such transition is connected with the generalized synchronization regime onset in coupled beam-plasma systems. 10,12 As it has been mentioned above, the amplification of the response vircator output power is related to the rising of the charged particle bunching efficiency while propagating through the drift space. The same amplification mechanism has been shown in the previous work 38 where we have investigated theoretically and experimentally the dynamics of the low-voltage vircator driven by the external harmonic signal.…”

“…The study of chaotic synchronization in the coupled beam-plasma systems is one of the most interesting and intricate problems of modern physics of plasmas and microwave vacuum electronics. [1][2][3][4][5][6][7][8][9][10][11][12] The regimes of chaotic synchronization in such systems have wide practical applications, for example, for creation of a powerful array of microwave oscillators, secure information transmission, and control of chaos in the microwave devices. [13][14][15][16][17][18][19][20][21][22][23] Several types of the synchronous behavior in coupled chaotic beam-plasma systems are known at present.…”

In this paper, we have studied the relationship between chaotic synchronization and microwave signal amplification in coupled beam-plasma systems. We have considered a 1D particle-in-cell numerical model of unidirectionally coupled beam-plasma oscillatory media being in the regime of electron pattern formation. We have shown the significant gain of microwave oscillation power in coupled beam-plasma media being in the different regimes of generation. The discovered effect has a close connection with the chaotic synchronization phenomenon, so we have observed that amplification appears after the onset of the complete time scale synchronization regime in the analyzed coupled spatially extended systems. We have also provided the numerical study of physical processes in the chain of beam-plasma systems leading to the chaotic synchronization and the amplification of microwave oscillations power, respectively.

“…High Speed Output Signal: Superlattices are ideal elements for sub-THz and THz electronics, while its signal output rate can match the transmission rate of 5G. Chaotic Synchronization: There are also chaotic synchronization characteristics in superlattices [10]. Under the same excitation signal, matched semiconductor can produce highly similar output signals.…”

“…Under the same excitation signal, the matched superlattice chip can produce chaotic synchronization signal. These chaotic synchronization signals are highly similar to each other [10], which are an ideal signal sources for generating symmetric keys. The inherent random fluctuation of molecular level in the formation process of superlattice materials makes it physically unclonable, which can be used to construct physical unclonable function (PUF) to ensure the security of symmetric keys.…”

Many Internet of things application scenarios have the characteristics of limited hardware resources and limited energy supply, which are not suitable for traditional security technology. The security technology based on the physical mechanism has attracted extensive attention. How to improve the key generation rate has always been one of the urgent problems to be solved in the security technology based on the physical mechanism. In this paper, superlattice technology is introduced to the security field of Internet of things, and a high-speed symmetric key generation scheme based on superlattice for Internet of things is proposed. In order to ensure the efficiency and privacy of data transmission, we also combine the superlattice symmetric key and compressive sensing technology to build a lightweight data transmission scheme that supports data compression and data encryption at the same time. Theoretical analysis and experimental evaluation results show that the proposed scheme is superior to the most closely related work.

“…Coupling to the resonant circuit significantly modifies this part of the current-voltage characteristics by generation of a series of additional peaks. Previously it was shown that these features relate to the development of additional instabilities in the system, which can lead to emergence of chaos [7,49].…”

Chaos, Solitons and Fractals, 104, Additional Information:• This paper was accepted for publication in the journal Chaos, Soli- AbstractThe spatially discrete-continuous dynamical systems, that are composed of a spatially extended medium coupled with a set of lumped elements, are frequently met in different fields, ranging from electronics to multicellular structures in living systems. Due to the natural heterogeneity of such systems, the calculation of Lyapunov exponents for them appears to be a challenging task, since the conventional techniques in this case often become unreliable andPreprint submitted to Elsevier August 31, 2017inaccurate. The paper suggests an effective approach to calculate Lyapunov exponents for discrete-continuous dynamical systems, which we test in stability analysis of two representative models from different fields. Namely, we consider a mathematical model of a 1D transferred electron device coupled with a lumped resonant circuit, and a phenomenological neuronal model of spreading depolarization, which involves 2D diffusive medium. We demonstrate that the method proposed is able reliably recognize regular, chaotic and hyperchaotic dynamics in the systems under study.
