Abstract
Disclosed herein is an electromagnetic wave shielding dielectric film. The electromagnetic wave shielding dielectric film includes a lower layer and an upper layer. The lower layer is formed of a dielectric in a plate shape. The upper layer is formed of a dielectric stacked on the lower layer, and is configured to form a periodic pattern of protrusion and depression structures.
Claims22
An electromagnetic wave shielding dielectric film, comprising:
- a lower layer formed of a dielectric in a plate shape;
- and
- an upper layer formed of a dielectric stacked on the lower layer and configured to form a periodic pattern of protrusion and depression structures,
- wherein the protrusion and depression structures form groove portions in a periodic pattern on upper and lower surfaces of the upper layer, and the groove portions on the upper and lower surfaces are spaced apart and alternately arranged at regular intervals,
- each of the groove portions on the upper surface has a groove structure in which two groove structures successively neighbor each other, and
- each of the groove portions on the lower surface has a single groove structure.

An electromagnetic wave shielding dielectric film, comprising:
- a first shielding film including a first lower layer formed of a dielectric in a plate shape, and a first upper layer formed of a dielectric stacked on the first lower layer and configured to form a periodic pattern of protrusion and depression structures;
- and
- a second shielding film including a second lower layer formed of a dielectric in a plate shape and stacked on the first upper layer, and a second upper layer formed of a dielectric stacked on the second lower layer and configured to form a periodic pattern of protrusion and depression structures;
- wherein the electromagnetic wave shielding dielectric film has a multilayer structure in which a plurality of shielding films are stacked,
- the protrusion and depression structures form groove portions on upper and lower surfaces of each of the upper layers of the first and second shielding films in periodic patterns, and the groove portions on the upper and lower surfaces of each of the upper layers of the first and second shielding films are spaced apart and alternately arranged at regular intervals,
- each of the groove portions on an upper surface of each of the upper layers of the first and second shielding films has a groove structure in which two groove structures successively neighbor each other, and
- each of the groove portions on a lower surface of each of the upper layers of the first and second shielding films has a single groove structure.
