RF shielding refers to the practice of blocking or reducing the transmission of radio frequency (RF) signals. This is important in various applications, such as protecting sensitive electronic equipment from interference or ensuring privacy in communication systems. Materials like metal, conductive coatings, and specialized fabrics are commonly used to create effective RF shields. The effectiveness of RF shielding is measured in decibels (dB), indicating how much signal reduction occurs. Proper design and installation are crucial to ensure that the shielding is effective across the desired frequency range. This technology is widely used in industries like telecommunications, healthcare, and military applications.
