Detailed Description

Example 1

As shown in fig. 1 and fig. 2, this embodiment is a laminated electromagnetic wave lens, in which a plurality of splicing layers 1 are laminated to form a body 2 of the lens, each splicing layer 1 is made of a low dielectric constant material, each splicing layer 1 is specifically made of a foam material having a dielectric constant less than 1.3, the thickness of each splicing layer 1 is 7mm, dielectric particles 4 are distributed in each splicing layer 1, the dielectric particles 4 are ceramic particles, the dielectric particles 4 form a three-dimensional spherical lens body 3, the body 2 is a cylindrical structure or a prismatic structure, and the spherical lens body 3 is a spherical structure; the distribution structure of the media particles 4 in the splice layer 1 is: a plurality of concave positions 5 are formed on the splicing layer 1, the medium particles 4 are of spherical structures, and one medium particle 4 correspondingly falls into one concave position 5. The face that is used for range upon range of laminating on each concatenation layer 1 is binding face, and concave position 5 on the concatenation layer 1 sets up on its binding face, makes a plurality of concatenation layer 1 range upon range of and can hide medium granule 4 after constituting main part 2 like this, what need explain here all has 2 binding faces on each concatenation layer 1 that is located the intermediate position, can be on 1 binding face or 2 binding faces on each concatenation layer 1 that is located the intermediate position be equipped with concave position 5. Because the medium particles 4 are of spherical structures, after the medium particles 4 are placed on the splicing layer 1 in the manufacturing process, the medium particles 4 can roll on the splicing layer 1 and finally fall into the concave positions 5, and the assembly of the medium particles 4 and the splicing layer 1 is very convenient; in addition, the splicing layer 1 is made of low-dielectric-constant materials, the structure weight of the splicing layer 1 embedded with the medium particles 4 and the structure weight of the existing structure for forming through holes in the flaky high-dielectric-constant materials are greatly reduced, the carrying is facilitated, and the use is more convenient.

In order to avoid the situation that 2 or more medium particles 4 fall into one pit 5, the overall dielectric constant of the spherical lens body 3 can be changed according to a set rule, as shown in fig. 2, the depth of the pit 5 on each splicing layer 1 is D1, and D1 is 5 mm; the diameter of the medium particles 4 is D2, and the diameter D2 is 4 mm.

The medium particles 4 on each splicing layer 1 and the concave positions 5 are positioned through interference fit. With this arrangement, when the media particles 4 roll to drop a portion thereof into the recesses of the pockets 5 during use, the media particles 4 can be pressed by a plate member to squeeze the media particles 4 into the pockets 5.

It should be noted here that the dielectric constant of the three-dimensional spherical lens body 3 should be continuously changed from 2 to 1 from the center to the outer surface thereof according to a certain mathematical rule, and the center of the spherical lens body 3 in the stacked electromagnetic wave lens is the center thereof. The laminated electromagnetic wave lens has the following two modes in production, namely that the dielectric constant of the spherical lens body 3 continuously changes from 2 to 1 from the center to the outer surface according to a certain mathematical rule: one is, as shown in fig. 3, the distribution of the pits 5 on each of the splice layers 1 is changed from sparse to dense from the edge to the center of the splice layer 1, in this way, the pits 5 on each of the splice layers 1 may be the same in size, so that the dielectric particles 4 with the same dielectric constant may be arranged on the splice layer 1, and the number and distribution density of the dielectric particles 4 arranged in a unit area on the splice layer 1 are set so that the dielectric particles 4 closer to the center of the spherical lens body 3 are arranged more densely, so that the dielectric constant of the position closer to the center of the spherical lens body 3 is larger, and the dielectric constant of the position farther from the center of the spherical lens body 3 is smaller; alternatively, the dielectric constant of the dielectric particles 4 on each of the splice layers 1 changes from low to high from the edge to the center of the splice layer 1, as shown in fig. 4, in this way, the concave positions 5 on each of the splice layers 1 may be the same in size and uniformly distributed, by using a plurality of dielectric particles 4 with different dielectric constants, the dielectric particles 4 with the dielectric constant close to 2 are arranged closer to the center of the spherical lens body 3, and the dielectric particles 4 with the dielectric constant closer to 1 are arranged closer to the outer surface of the spherical lens body 3.
