Title:
ELECTRIC WAVE ABSORPTION SHEET
Document Type and Number:
Japanese Patent JP2019195083
Kind Code:
A
Abstract:
To realize an electric wave absorption sheet, capable of well absorbing electric waves of high frequencies above a millimeter wave band, easy to handle.SOLUTION: The electric wave absorption sheet includes a flexible electric wave absorption layer 1 including a particulate electric wave absorption material 1a and a resin binder 1b. The electric wave absorption sheet is of a non-resonant type for absorbing electric waves transmitted through a sheet without a reflective layer for reflecting electric waves. The electromagnetic wave absorption material is a magnetic iron oxide that magnetically resonates in a frequency band greater than or equal to the millimeter wave band.SELECTED DRAWING: Figure 1
