“…As it was shown earlier [3][4][5], the metamaterial formed by two serially connected planar photonic crystals with some certain parameters possess a set of passbands and stopbands in the spectrum of transmission coefficient. The narrow resonance transmission peak, identified as electrodynamic analog of known "Tamm state", appears in one of stopbands of the transmittance spectrum of the metamaterial.…”

At present, the fast contactless identification of liquids enclosed into a container has a practical importance. The identification of liquids can be required, for example, at airports, in order to prevent the transport of illicit liquids in bottles. However, the complexity of applying contactless methods lies in the difficulties to take into account the influence of container characteristics. In this paper, a metamaterial based on two planar photonic crystals (PPC) has been applied for the experimental analysis of liquids in different containers. It was shown experimentally how the transmission coefficient spectrum of PPC varied with changing the characteristics of a container with a liquid. Namely, the influence of thickness and material of the container walls and the inclination angle of its axis relative to the metamaterial plane on the transmission coefficient has been studied. The reliable differing of concentration increments of edible salt and sugar in water was determined as 10 %. It is shown that an increase of the container walls thickness leads to a decrease of the reliability of the liquid identification in it. Thus, the influence of some container characteristics on the reliability of contactless identification of liquids by using PPC has been taken into account.

“…This prevents its introduction everywhere. A prospective alternative to this design is a metamaterial based on planar photonic crystals (PPC) [3][4][5]. It possesses the simplicity of fabrication, low cost, quite small dimensions, while maintaining sensitivity to the liquids identification.…”

“…Состояния Тамма могут также встречаться на границе двух соединенных фотонных кристаллов с различными размерами элементарных ячеек при перекрытии запрещенных зон этих двух кристаллов [10,14]. Существование таммовского поверхностного состояния на поверхности между двумя фотонными кристаллами экспериментально наблюдалось авторами [12,15].…”

“…В работе [15] исследовано соединение двух микрополосковых СВЧ фотонных кристаллов, имеющих различные размеры элементарных ячеек, а именно имеются элементы с широкими и узкими верхними полосками микрополосковых линий передачи, длины элементов с широкими полосками различны в одном и другом фотонном кристаллах, а длины элементов с узкими полосками одинаковы. При теоретическом расчете и в эксперименте на границе двух фотонных кристаллов без нарушений включался элемент с узким полоском микрополосковой линии, длина которого отлична от длины элементов с узкими полосками, входящих в состав обоих фотонных кристаллов.…”

Представлены результаты экспериментального исследования и расчета таммовских поверхностных состояний в брэгговской гетероструктуре, образованной из двух групп периодически расположенных отрезков волноводно-щелевой линии передачи, имеющих разные размеры. Установлено, что в " идеальной" брэгговской гетероструктуре таммовские поверхностные состояния не возникают, таммовские поверхностные состояния возникают при наличии на границе двух брэгговских структур интерфейсного элемента с характеристиками, отличными от характеристик как одной, так и другой брэгговской структуры.

“…We study transmission spectra of the sample at normal wave incidence in the spectral range of 22-40 GHz using the vector network analyzer (N5230A) and two broadband horn antennas. To measure the transmission spectra the comprehensive experimental technique based on the scanning module was designed and described by authors in [15,16]. In this structure, only the fundamental wave propagates at the frequencies lower than 40 GHz, the other diffraction orders are damped.…”

We report on a new class of mechanically tunable planar metamaterials comprising resonating units formed by crossed metallic strip gratings. We observe a resonant response in transmission spectra of a linearly polarized wave passing through the system of crossed gratings. Each grating consists of an array of parallel metallic strips located on the top of a dielectric substrate. It is revealed that the resonant position appears to be dependent on the angle of gratings crossing. It is found out both theoretically and experimentally that the resonant shift on the frequency scale appears as a result of increasing in the length of the resonating portion of the parallelogram periodic cell formed by the crossed metallic strips with decreasing crossing angle and the proposed design can be used in new types of planar metamaterials and filters.In recent decades, a huge number of publications appeared which are related to the study of the optical properties of metamaterials. Metamaterials are composites possessing characteristics that cannot be found in nature (see, for instance, [1,2] and references therein). In such artificial systems the unit cell serves as an atom or molecule in conventional natural materials, whereas it can be adjustable through varying cell's geometry and constituents. Those of them that are produced by planar technology remains among the most promising for applications. They are also known as metasurfaces [3,4].Typically metasurfaces manifest a resonant response due to excitation of the magnetic and/or electric modes. This resonant response of metasurfaces is a cornerstone for achieving exotic behaviors which are dependent on the composition and structure of the structures' unit cell [5,6].
