Electromagnetic wave absorber, IT foam, directional electromagnetic wave absorber, Wi-Fi countermeasures.

Electromagnetic wave absorber, IT foam, directional electromagnetic wave absorber, Wi-Fi countermeasures.

It is an electromagnetic wave absorber made of olefin-based resin foam, which exhibits excellent effects in suppressing wideband characteristics, is easy to cut and install on-site, and reduces multipath.

- It is capable of wideband radio wave absorption from 300 MHz to 110 GHz and excels in radio wave absorption performance for oblique incidence. It is easy to cut and process, making installation at the site straightforward. - It is an electromagnetic wave control material and radio wave absorber effective for wireless technology, EMC, and noise countermeasures. - Made primarily from polyolefin resin and carbon, it can be manufactured in suitable thicknesses according to the applicable frequency. - Wireless LAN access points stored in the ceiling can cause interference due to reflected waves from the deck plate within the ceiling; the radio wave absorption box cuts off upward radio waves, enhances the directionality of downward waves, and absorbs excess radio waves. - Installing it on adjacent partition walls in the same floor tenant prevents radio wave interference and secures channels. - Near glass windows, it prevents radio wave leakage to the outside, and by using it in conjunction with shielding films and SS sheets on the floor, it reduces radio wave interference between floors and inside and outside. - The box for wireless LAN access points, when combined with SS sheets, prevents radio wave interference. - It is used as an electromagnetic wave control material for adjusting wireless LAN access point equipment during system installation (used to isolate and adjust several units at hand).

Electromagnetic Wave Absorber "E&CVHP-NRL" [Compatible with a wide range of incident angles!]

Electromagnetic Wave Absorber "E&CVHP-NRL" [Compatible with a wide range of incident angles!]

Pyramid-shaped electromagnetic wave absorbers! Perfect for covering measurement devices and antenna support structures in dark rooms to suppress unwanted reflections! We are currently giving away samples in a lottery!

E&C VHP is a foam polyurethane absorber with internal filling (not hollow), pyramid shape, and carbon filling. It is ideal for covering measurement devices and antenna support structures in anechoic chambers for constructing radio wave anechoic rooms or suppressing unwanted reflections. It exhibits the highest performance in broadband frequency characteristics among various absorbers for both vertical incidence and a wide range of incident angles. 【Specifications】 ■ Frequency range: 120MHz to 24GHz ■ Absorption characteristics: up to -50dB *For details, please request materials or view the PDF data from the download.

Radio Wave Absorber "E&C SPY-NRL"

Radio Wave Absorber "E&C SPY-NRL"

Broadband, pyramid-shaped, open-cell foam electromagnetic wave absorber

E&C SPY is a high-performance pyramid-shaped electromagnetic wave absorber made from lightweight open-cell foam material, designed for medium power density applications. Its shape and electrical properties are equivalent to those of E&C VHP. E&C SPY is suitable for medium power density applications. Compared to E&C VHP, it has a greater amount of open-cell structure, allowing for better air circulation between cells, and maintains a moderate average temperature even when exposed to medium power densities of up to 8 kW/m². For applications with higher power densities, we recommend the honeycomb-structured E&C HFX-HC pyramid-shaped absorber. 【Specifications】 ○ Frequency range: 400MHz to 9GHz ○ Absorption characteristics: up to -50dB For more details, please contact us or download the catalog.

Radio Wave Absorber "E&C FHY-NRL"

Radio Wave Absorber "E&C FHY-NRL"

Flat hybrid electromagnetic wave absorber

E&C FHY is a thin, flat, multi-layer hybrid absorber developed for EMC anechoic chambers. It consists of a thin and lightweight matching layer and a flat protective top plate. This design allows it to be used on top of ferrite, providing sufficient performance for EMC anechoic chambers in the frequency range from around 30 MHz to 2 GHz. For applications requiring wideband performance from around 30 MHz to over 30 GHz, the optimal absorbers are E&C VHY or E&C HX, which can be selected based on the available space. 【Specifications】 ○ Frequency Range: 30 MHz to 2 GHz ○ Absorption Characteristics: up to -40 dB For more details, please contact us or download the catalog.

Wave+X Electromagnetic Wave Absorber

Wave+X Electromagnetic Wave Absorber

A radio wave absorber crystallized with new principles and technologies.

"Wave+X" is a radio wave absorber that can eliminate unnecessary radio waves, acting as a traffic controller for radio waves to establish a good communication environment. It plays a central role in the Advanced Traffic Management System (ITS) and has a proven track record of being implemented in the ETC system. Furthermore, it is expected to be widely deployed in the future at gas stations, for fee payments, in convenience stores, for drive-thru fee payments, and for vehicle-to-infrastructure information distribution. Additionally, compared to conventional radio wave absorption sheets and panels, it is thin yet demonstrates absorption performance exceeding that of vertical incidence at various angles, starting from high incident angles of over 40 degrees. 【Features】 ■ Establishes communication environment ■ Eliminates unnecessary radio waves ■ Thin design ■ Exhibits absorption performance exceeding vertical incidence *For more details, please contact us or download the catalog.
