Drastic improvements have been made to the flexibility, light transmittance and absorption of electromagnetic waves in millimeter-wave and sub-THz bands. The design parameter of the EM-wave absorption sheet has been adjusted to a set reflection decrement of -20 dB aim with the target frequency of...
2, we calculated the reflection, transmission, and absorption spectra of the proposed design at 358 K. It is clear that in this working mode, the transmission spectrum values (blue dotted line) from 0.3 to 1.5 THz are almost 0, which demonstrates that a 1 µm-thick metallic state VO2 ...
1. The proposed metasurface comprised an array of complementary C-shaped split-ring resonators (CSRRs) made of indium tin oxide (ITO) and a continuous ITO film, separated by a polymethyl methacrylate (PMMA) spacer. The transfer-matrix method and a multiple reflection and transmission interference ...
In the expression (1), nav is an average refractive index in a plane orthogonal to the helical axis and “p” is a helical pitch in a helical structure of the liquid crystal molecule. The band width Δλ of a reflection wavelength is represented by the following expression (2): Δλ=Δ...
2.4 Near-zero and approaching-infinity mass density Another type of acoustic metamaterial is explained in Fig. 1e with near-zero effective mass density. Ideally, this class of metamaterials enables zero refractive index and infinity phase velocity, leading to wave propagation without any reflection an...
Grating metasurface is a structure formed by combining a grating with metasurface, and high efficiency polarization control can be achieved by using the grating as a unit structure with different rotation angles. By stacking single-layer wave plates as single-frequency modulators, a broadband modulator...
We develop a quantum theory describing the input–output properties of Josephson traveling wave parametric amplifiers. This allows us to show how such a device can be used as a source of nonclassical radiation, and how dispersion engineering can be used
Fig. 3. Absorption at different structural dimensions parameter values of MA:(a) d2, and (b) d3. Theoretical analysis and discussion The structural model of the proposed absorber is applicable to multiple reflection theory (MIRT) [56]. Therefore, the MIRT model of the MA absorber is shown...
(i) said particle p has one or more of the following interactions with said wave guide w: (i) transmission, (ii) reflection, (iii) emission, (iv) absorption, and (v) adsorption; (vi) such an interaction that the emission of radiation of wavelength λ, meeting the condition λ>λc1 ...
