Metamaterials on Helix Structures with Abnormal Dispersion
P. 474–476.
Reasons of appearance and possible ways of frequency dispersion control in
metamaterials based on helix structures with the help of a longitudinal propagation ground
plane and a ground plane with capacitive conductivity in azimuth direction are considered. It is
shown that existence of metamaterial constructions based on helix systems with abnormal
dispersion is a perspective way of reduction if devices longitudinal dimensions keeping the same
time their electrodynamics characteristics and parameters. In the case with frequency rise up
the wave phase velocity also increases keeping the structure electrical length and the presence of
slow-wave coefficient allows structure dimensions decreasing.

We explore experimentally a quantum metamaterial based on a superconducting chip with 25 frequency-tunable transmon qubits coupled to a common coplanar resonator. The collective bright and dark modes are probed via the microwave response, i.e., by measuring the transmission amplitude of an external microwave signal. All qubits have individual control and readout lines. Their frequency ...

The analysis of single-mode photon fluctuations and their counting statistics at the superradiant phase transition is presented. The study concerns the equilibrium Dicke model in a regime where the Rabi frequency, related to a coupling of the photon mode with a finite-number qubit environment, plays the role of the transition's control parameter. We use the ...

This paper presents a computer model of a FSS based on mushroom-shaped metamaterial. The model is based on the calculation of equivalent distributed inductance and distributed capacitance of the unit cell of the surface according to its geometric dimensions. The computer model is realized as the “META” program based on MathCAD ver.15 software and provides ...

NaCl is one of the simplest compounds and was thought to be well-understood, and yet, unexpected complexities related to it were uncovered at high pressure and in low-dimensional states. Here, exotic hexagonal NaCl thin films on the (110) diamond surface were crystallized in the experiment following a theoretical prediction based on ab initio evolutionary algorithm USPEX. State-of-the-art ...

В данной монографии развиваются теоретические основы метода структурного моделирования применительно к метаматериалам. Этот метод учитывает параметры кристаллической решетки, размеры частиц среды, их форму и константы силовых взаимодействий между ними и поэтому является наиболее подходящим для изучения влияния размерных эффектов на физико-механические свойства материала. Построенные математические модели метаматериалов позволяют не только получить представление о качественном влиянии ...
