A broadband electromagnetic wave absorption sheet that absorbs millimeter waves across a wide frequency range with this one sheet.
This is a sheet-type electromagnetic wave absorber that can be used for noise countermeasures in millimeter-wave radar, millimeter-wave sensing, information communication devices (Beyond 5G), and more. Unlike conventional products that absorb only specific frequencies, this sheet can absorb a wide range of millimeter waves extending to several tens of GHz, allowing it to accommodate multiple devices with different frequencies using just one sheet. The design of the sheet also allows for adjustment of the absorption frequency to the desired band. It is lightweight and flexible, making it possible to process into any shape, and can be attached to various locations by providing an adhesive layer.
