Embodiment 1
[0031] In this embodiment, the production of a spherical Lunberg lens with 5 dielectric layers is taken as an example. Such a Lunberg lens is sequentially composed of a spherical core, a first dielectric layer, a second dielectric layer, a third dielectric layer, a fourth dielectric layer and a fifth dielectric layer from the inside to the outside. The materials corresponding to the spherical core and these medium layers in turn are: the first granular material, the second granular material, the third granular material, the fourth granular material, the fifth granular material and the sixth granular material. Wherein, the dielectric constants of the first granular material to the sixth granular material are from high to low, wherein, the dielectric constant of the first granular material is 2, and the dielectric constant of the sixth granular material is 1.
[0032] Its processing method is as follows:
[0033] Step 1): A first-stage ball is made by sticking a certain amount ...
Embodiment 2
[0042] In this embodiment, an ellipsoidal Lunberg lens with four dielectric layers is taken as an example.
[0043] It differs from Example 1 in that: a number of first granular materials are bonded into an ellipsoid by an adhesive to form a first-stage ball, and the first-stage ball grows into a second-stage ball During the process, the ball in the second stage finally becomes an ellipsoid, including the ball in the third stage and the ball in the fourth stage finally become an ellipsoid.
