Radio wave absorption sheet, electromagnetic wave absorption sheet, high-frequency countermeasure sheet, noise suppression.
The thin sheet that absorbs high-frequency electromagnetic waves excels in radio wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability.
In recent years, the number of electronic devices and radar emitters that emit high-frequency waves has increased, and correspondingly, EMC and EMS measures have become essential. The "high-frequency compatible electromagnetic wave absorption sheet" absorbs electromagnetic waves in the gigahertz range of 5 to 110 GHz. It can be customized in terms of materials, mixing ratios, and film thickness for the electromagnetic wave absorption layer and metal reflection layer to match the frequencies emitted by electronic devices. As the speed of CPUs and other components increases, the noise frequency range is shifting to high frequencies, making it difficult for traditional ferrites and filters to prevent interference with signal waveforms, complicating noise countermeasures. This product excels in radio wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability. It is suitable for countermeasures against module TX-RX crosstalk (ETC at 5.8 GHz, X-band at 8-12 GHz, ship radar at 3 GHz and 9 GHz, proximity radar at 24 GHz, local 5G at 28 GHz, high-speed wireless LAN at 60 GHz, vehicle-to-vehicle radar at 76.5 GHz, and millimeter-wave noise countermeasures from 50 GHz to 110 GHz), ground plate crosstalk countermeasures, unwanted radiation noise absorption, communication facility sites, countermeasures against ETC misoperation due to reflection, and ghosting issues caused by nearby metal structures in radar applications.

Detailed information

Electromagnetic Wave Noise Suppression Sheet: In small electronic devices such as mobile phones, laptops, and digital cameras, issues arise due to high-density mounting of electronic components, increased clock speeds, and the use of low-voltage ICs for power-saving purposes, leading to unwanted radiation in the high-frequency range and complex electromagnetic interference between components and circuits. The noise suppression sheet addresses these issues by uniformly orienting flat powders of soft magnetic materials with high permeability within a resin material, while electrically isolating the powders from each other. When this sheet is placed in areas experiencing electromagnetic interference, inductive coupling is suppressed, high-frequency noise is attenuated, and unwanted radiation can be effectively suppressed without secondary effects such as secondary radiation or signal degradation.
