To design their novel acoustic metamaterial, the team 3D-printed a series of small trimers, arranged and connected in a triangular lattice. Each trimer unit consisted of three acoustic resonators.
A conformation C of n residues can be expressed in the form of movement direction such as C e {F, B, U, D}(n-1) and C e {F, B, U, D, FU, BU, BD, FD}(n-1) for two-dimension square and triangular lattice, respectively.
In this paper, our PC waveguide is operated at 1,550 nm [31], and our PC waveguide is constructed using a 2D triangular lattice array of air holes embedded in polysilicon (p-Si).
The sub-wavelength resolution of an imaging effects have been demonstrated experimentally [6-9] and theoretically [4, 10-16] for triangular lattice, square lattice and hexagon lattice PCs.
The grain growth Monte Carlo simulation is performed on a two-dimensional triangular lattice, where for each lattice site "i" a number [S.sub.i] is assigned which corresponds to the grain orientation [10, 11].
On the diffraction pattern of POVs the formation of a truncated triangular lattice can be seen, in which the number of the spots along an edge of the triangle minus one represents the topological charge of the incident POV [38].
It is well known to us that in usual triangular lattice PCF the conventional notations of air-hole diameter are "d" and hole-to-hole distance is "[LAMBDA]." In the analysis of the present square-lattice PCF structures, we use [LAMBDA] as the hole-to-hole spacing in horizontal or vertical direction with d as the diameters of the air holes.
Using source code from the Open Source Physics library written in Java as a basis, I have developed a series of simulations to computationally calculate the critical probability in both a conventional triangular lattice (pc = 0.5), as well as in a non-trivial lattice such as the kagome lattice (pc = 0.65).
In this work, we present the surface plasmas excitation of the SHG in three-dimensional triangular lattice structures consisting of noncentrosymmetric split-ring resonators.
