The reflectance of coding a and b are less than -10 dB on average in the frequency range of 5.8-15.5 GHz under normal incidence, which presents an excellent broadband RCS reduction characteristic compared with other works [6][7][8]. The RCS reduction is greater than 10 dB in the frequency range of 5.5-15 GHz under normal incidence.…”

“…On the whole, the simulated and measured curves of coding a and b are consistent well in the entire frequency range of 2-18 GHz, which reveals the polarization-insensitivity of matrix-type random coding MS. The reflectance of coding a and b are less than −10 dB on average in the frequency range of 5.8-15.5 GHz under normal incidence, which presents an excellent broadband RCS reduction characteristic compared with other works [6][7][8].…”

“…As a two-dimensional artificial material, metasurface (MS) is composed of sub-wavelength element array [1][2][3][4], which has been widely applied in optoelectronics devices [5][6][7][8][9][10], such as sensor, detector, etc. Because of its ability to effective manipulation of electromagnetic (EM) waves, MS can be especially applied in radar stealth field [11][12][13][14].…”

In this paper, we present a design of the linear polarization conversion metasurface (MS) for the broadband radar cross section (RCS) reduction based on split-ring resonator (SRR) structure in microwave region. The corresponding phase gradient can be obtained through the stable phase difference of basic units of polarization conversion MS. The designed polarization conversion MS is applied in coded electromagnetic (EM) matrix by defining two basic units “0” and “1”, respectively. Based on the principle of planar array theory, a new random coding method named by matrix-type coding is proposed. Correlative RCS reduction mechanism is discussed and verified, which can be used to explore the RCS reduction characteristic. The simulated linear polarization conversion rate of the designed structure is up to 90% in the frequency range of 6–15 GHz, and the RCS reduction results verify the theoretical assumptions. Two kinds of matrix-type coding MS samples are prepared and measured. The experimental results indicate that the reflectance of MS is less than –10 dB on average under normal incidence in frequency range of 5.8–15.5 GHz. The average RCS reduction is essentially more than 10 dB in frequency range of 5.5–15 GHz and the corresponding relative bandwidth is 92.7%, which reasonably agrees with simulation. In addition, excellent RCS reduction characteristic of the designed MS can also be achieved over a wide incident angle.

“…In addition, there may also be a fabrication error. Our analysis method can be used in the research of aperture antennas enclosed by the radome, terahertz sensors and any materials protected by the dome structure, and multi-physics problems [22][23][24][25][26]. Figure 9 illustrates the radiation patterns of the 3 × 3 cavity-backed circular aperture array antenna with the designed FSS and dielectric radomes.…”

Radiation from a cavity-backed circular aperture array antenna enclosed by a frequency selective surface (FSS) radome is studied using the hybrid analysis method, by combining the mode matching method, the ray tracing technique, and Huygens's principle. The equivalent magnetic surface currents on the apertures are derived from the aperture electromagnetic fields, which are calculated based on the mode matching method. The rays are generated from the equivalent magnetic surface currents and used to analyze the FSS radome based on the ray tracing technique. After being obtained from both the mode matching method and the ray tracing technique, electromagnetic fields on an outermost radome are transformed into the equivalent electric and magnetic surface currents using Huygens's principle. The radiated fields are computed from the equivalent surface currents and compared with the measured data.

An effective way of decontamination using optical metamaterials like photonic crystals consisting of glass microspheres or granulated quartz with various geometries is proposed. The efficient decontamination using the evanescent zone of metamaterials opens a new perspective in pathogen decontamination. We propose different topological structures of metamaterials to enlarge the contact surface of ultraviolet radiation with polluted translucent fluids. The approach is based upon the increased transfer of UV radiation via evanescent waves of metamaterials into contaminated translucent fluids. A series of experimental estimations of the decontamination rate of this type of metamaterials have been made. For these investigations, a decontamination core filled up with metamaterials is used through which the contaminated fluid freely flows. Experiments have conclusively proved that evanescent zone of quartz and optical fiber metamaterials can effectively inactivate Coliform (including Escherichia coli), or Enterococcus bacteria, as well as yeast and Kombucha cultures.
