From our smartphones to Wi-Fi routers, RF waves are omnipresent. But did you know that excessive exposure to RF radiation could potentially harm our health? In this blog post, we’ll learn why blocking RF is crucial for safeguarding our well-being and explore effective EMF remediation products to shield ourselves from its effects. So, let’s understand the importance of RF protection and discover how we can take control of our health in a wireless world.
What Can Be Used as an RF Blocker?
Both RF shields and RF absorbers contribute to safeguarding devices from RFI. The distinction lies in their methods of RF blocking.
RF Shields
An RF shield serves a single purpose: blocking RF signals. Typically made of metal, though occasionally crafted from plastic, it forms an enclosed barrier safeguarding RF-sensitive components within. Alternatively, it can envelop an RF-emitting device to prevent RF signals from escaping and disrupting nearby electronics.
Examples of RF shields range from the Faraday cage found in household microwaves to the specialized facilities housing MRI machines. However, custom-built RF shields are predominant in defense, aerospace, medical devices, and telecommunications industries. This diversity ensures a variety of RF shield types for various device designs.
RF Absorbers
In contrast, RF absorbers are relatively simpler devices. Usually consisting of magnetic sheet stock, they are affixed to a device’s surface akin to a sticker. RF absorbers create an electric field around themselves by utilizing magnetic or elastomeric materials filled with conductive and ferromagnetic particles. When RF signals encounter them, they become polarized and are retained within the electric field, effectively absorbed.
Can RF Shields and RF Absorbers Be Used Together for Blocking RF?
RF shields and RF absorbers are dual solutions to the same issue: RFI. Hence, they are frequently utilized together on devices. Since both contribute to RF blocking through different mechanisms, having both components on a sensitive device is typically beneficial. Additionally, RF absorbers are often applied to RF shields to bolster their RF blocking capabilities.
What Material Can Be Used for Blocking RF?
There are different materials for shielding against RF. The choice depends on the electronics and frequencies involved. Choosing the right material is important. Keep reading to learn about each and find the best for your needs.
