ABSTRACT In this Letter we show that the extraordinary optical transmission phenomenon found before in 2D hole arrays is already present in a linear chain of subwavelength holes, which can be considered as the basic geometrical unit showing this property. In order to study this problem, we have developed a new theoretical framework, able to analyze the optical properties of finite collections of subwavelength apertures and/or dimples (of any shape and placed in arbitrary positions) drilled in a metallic film.

    ABSTRACT: The transmission characteristics of free-standing metasurfaces consisting of square metal patch, which rotated 45° (which is defined as the rotated metasurfaces) or 0° (which is defined as the regular metasurfaces) around their array arrangement direction, have been studied at microwave frequencies. The proposed metasurfaces in vacuum environment, considered as free-standing planar frequency selective surfaces, are analyzed for searching its transmission characteristics with variable dimension at different frequencies. For the rotated metasurfaces, a bizarre phenomenon, in which transmission will increase inversely as the size of the rotated square metal patch is increased, can be observed at the periodicity of these arrays between 2λ/3 and 4λ/5, where λ is the considered wavelength. But for the regular metasurfaces, this phenomenon cannot be observed. In addition, the rotated metasurfaces and the regular metasurfaces loading on infinite resistive sheet are also studied for discussing its transmission and reflection properties with similar conditions. It is found that the regular metasurfaces loading on infinite resistive sheet show almost linear variable electromagnetic characteristic with the variable size of the regular metasurfaces at a broad frequency range. However, because of the scattering mechanism of evanescent diffraction, the similar linear relationship of electromagnetic characteristic cannot be obtained from the rotated case. These results can be used as a guide for realizing tensor impedance surfaces with various gradient properties.

    ABSTRACT: We demonstrate perfect transmission of sound through a rigid barrier embedded with Helmholtz resonators. The resonators are confined within a waveguide and they are oriented such that one neck protrudes onto each side of the barrier. Perfect sound transmission occurs even though the open area of the necks is less than 3% of the barrier area. Maximum transmission occurs at the resonant frequency of the Helmholtz resonator. Because the dimensions of the Helmholtz resonators are much smaller than the resonant wavelength, the transmission is independent of the direction of sound on the barrier and of the relative placement of the necks. Further, we show that the transmitted sound experiences a continuous phase transition of π radians as a function of frequency through resonance. In simulations of adjacent resonators with slightly offset resonance frequencies, the phase difference leads to destructive interference. By expanding the simulation to a linear array of tuned Helmholtz resonators we show that it is possible to create an acoustic lens. The ability of Helmholtz resonator arrays to manipulate the phase of a plane acoustic wave enables a new class of sonic beam-forming devices analogous to diffractive optics.
