Are there any issues such as 'no radio wave absorbers that can support large-capacity communication,' 'degradation over time that prevents maintaining product quality for long periods,' or 'no radio wave absorbers that can be used in high-temperature environments'? The 'radio wave absorption ceramics' will solve all these problems. We have created a radio wave absorber that maximizes the properties of ceramics, supports high-speed large-capacity communication, allows for long-term outdoor use, and can be used in high-temperature environments. It can be used in locations such as communication base stations, outer space, and undersea cables, where conventional radio wave absorbers have struggled to perform. 【Comparison of Radio Wave Absorbers】 <Conventional> <Wicera> Rubber sheet ➡ Ceramics Aging changes present ➡ No aging changes Weak against heat ➡ Strong against heat with inorganic materials Up to about 30GHz ➡ Supports up to 100GHz etc. *For more details, please download the PDF or contact us.

"Radio wave absorbing ceramics" are a new type of radio wave absorbing material that does not emit gas like rubber or resin and can be used in high-temperature environments. Because they are made of ceramics, they do not degrade over time and excel in wear resistance, hardness, corrosion resistance, and weather resistance. They are suitable for environments with high data volumes, such as outer space and underwater cables, where maintenance is difficult once used, as they are compatible with millimeter wave frequencies ranging from 20GHz to 100GHz. 【Features】 - Usable in the millimeter wave frequency range of 20GHz to 100GHz - Does not emit gas and can be used in high-temperature environments - Excellent wear resistance, hardness, corrosion resistance, and weather resistance, etc. *For more details, please download the PDF or contact us.
