Electromagnetic wave lens and production method thereof

The invention relates to an electromagnetic wave lens comprising a body which comprises a plurality of dielectric layers. The dielectric layer comprises a base material and a dielectric body arranged in the base material, and the base material is a material which has good plasticity and stirring performance before being dried and is fixed in shape and disappears in plasticity after being dried; the dielectric constant of the dielectric body is higher than that of the base material, and the dielectric body is used for increasing the dielectric constant of the dielectric layer; the plurality of dielectric layers are wrapped layer by layer, and the dielectric constants of the dielectric layers are lower and lower from inside to outside. The electromagnetic wave lens has the characteristics of low production cost, high production efficiency, easiness in production of high-performance electromagnetic wave lenses with stable indexes and the like. The invention further relates to a production method of the electroma
