3D Electromagnetic Shielding Member With Wavelength-Selective Mesh

The patent applies curvature by forming the electromagnetic shielding member as a three-dimensional curved surface structure rather than a flat planar shape. This curvature enables the shielding member to conform to three-dimensional objects and achieve wavelength-selective reflection in multiple directions, resolving the limitation of planar structures while maintaining manufacturing feasibility through molding processes.

The patent transitions from a two-dimensional planar structure to a three-dimensional structure by adding spatial dimensionality. This dimensional change allows the shielding member to interact with electromagnetic waves from multiple angles and effectively reflect specific wavelengths to three-dimensional objects, overcoming the inherent limitation of flat surfaces.

The patent employs a porous or mesh-like conductive layer structure that allows selective transmission of electromagnetic waves. The patterned metal meshes create openings with specific geometries that enable certain wavelengths to pass through while blocking others, achieving wavelength-selective transmission without requiring complex multi-layer constructions.

The patent uses composite material structures combining conductive metal meshes with substrate materials to achieve both mechanical support and electromagnetic functionality. This composite approach integrates the conductive patterned layer with the base structure, reducing overall complexity compared to separate assembly of multiple functional layers.
