Embodiment 1
[0040] Example 1: Frequency doubling / chirality switch variable array of conductive microparticles
[0041] The top view of the plane where the variable array of conductive particles of the double frequency switch is located is shown in Fig. figure 1 , figure 2 shown. exist figure 1 , figure 2 Array 1 is represented by a solid line, and array 2 is represented by a dotted line. Both arrays 1 and 2 are composed of conductive particles of the same size. Each conductive particle is made of metallic silver and is a rectangular parallelepiped with a size of 150nm (length)*50nm. (width)*50nm (height), the horizontal and vertical repetition periods of the conductive particles in the array 1 and array 2 are both 728.8 nm, that is, the distance between every two adjacent conductive particles in the horizontal or vertical direction in the array 1 is 728.8 nm. Of course, the array The same is true for the second; however, the length and width of the conductive particles possessed by ...

[0043] Example 2: Variable Array of Adjustable Conductive Particles with Transflective Spectroscopy and Third-Order Nonlinear Optical Effects
[0044] The top view of the plane where the variable array of tunable conductive particles with transflective spectrum and third-order nonlinear optical effect is located is shown in the figure below. Figure 4 , Figure 5 shown. exist Figure 4 , Figure 5 Array 1 is represented by a solid line, and array 2 is represented by a dotted line. Array 1 and Array 2 are composed of conductive particles of the same size, which are cylinders. Each conductive particle is made of metallic silver, and the size is 100nm (diameter)* 100nm (high), the horizontal and vertical repetition periods are both 500nm, that is, the distance between every two adjacent conductive particles in the horizontal or vertical direction in array 1 is 500 nm, of course, the same is true for array 2; in array 1 or array 2, all particles are The geometric centers of al...
