Radio Absorbing Material for Next-Generation Wireless Devices

Abstract

Electrical and computer circuits are particularly susceptible to interference from a wide range of human or natural factors. Interference can occur as noise on communication equipment, flashing over televisions and computer monitors, errors in instrumentation, computer network compatibility problems, and electronic malfunctions. Material absorption and safety serve as a shield to prevent the intrusion of the radio wave from getting through critical components and ensure that electrical circuits perform as planned. Since radio frequency interference can also contribute to damage to infrastructure, proper safety and absorption can greatly increase the service life of electrical and electronic equipment. This paper presents a holistic view of the basic concepts of electromagnetic analysis and developments in radio absorbing materials.
