TL;DR: This work has shown that for the systems of mercury rods with square cross section in a water host, the width of lowest gaps increases as the rotation angle of the square rods increases, but opposite results are found for the inverse systems of water rods in mercury, where the lowest gaps narrow with an increase in the rotation angles.

TL;DR: In this paper, the point defect states of acoustic wave in two-dimensional arrays of water cylinders with circular (square) cross section in a mercury host were studied and the influence of the defect geometry on the defect band modes was investigated.

TL;DR: In this paper, the absolute elastic wave band gaps in three-dimensional systems consisting of steel inclusions embedded in plastic matrix were investigated and the configurations formed by inserting an additional steel object (either a sphere of different size or a cube) into each unit cell of a simple cubic structure with spherical inclusions were investigated.

TL;DR: Point defect modes of acoustic wave in two-dimensional square arrays of square water rods in a mercury host were studied and showed that for both square defect and circular defect, the defect modes are only related to the defect filling fraction F(d), but not with the geometry of defects (square or circular), as well as the orientations of the square defect.

TL;DR: In this article, the authors present band structure results for a new two dimensional (2D) rectangular array geometry of water (mercury) cylinders of square cross section in a mercury (water) host.
