RFI and EMI - Shielding and Absorbing materials are used in the application of 78134088. Broadly speaking RFI Shielding and EMI Absorbing materials can be divided into two domains: absorptive type (electromagnetic absorbing) and reflective type (reflective shielding). While each type of shielding and absorbing material is used to block or attenuate various electromagnetic fields, they all work to stop or reduce the possibility of interference between two or more electronic devices.

Absorptive Type – Electromagnetic Absorbing Materials

Electromagnetic absorbing is effective when the EMI waves, RFI pulses or other electromagnetic signals enter a device or pass through a bulkhead, an absorptive material such as metallic paint or carbon composites is used to absorb the EMI or RFI. This material is usually applied to the device in question, which can help stop electromagnetic signals from reaching the device or even stop the signals from even entering the device.

Reflective Type – Reflective Shielding Materials

Reflective shielding is perhaps the most common type of shielding used in 78134088. The purpose of this type of shielding is to reflect any EMI/RFI waves away from the target device. Reflective type material such as metal shielding is affixed to the target device and creates an outer barrier that reflects any electromagnetic fields away from the device. If the EMI/RFI waves are strong, then multiple layers of this type of shielding may be used to achieve maximum defense from interference.

Working Principle of RFI and EMI Shielding and Absorbing Materials

The way in which RFI and EMI shielding and absorbing materials work is fairly simple. With absorptive type materials, the material absorbs the electromagnetic fields, turning them into tiny currents of electricity, which dissipates the energy produced by the electromagnetic field. For reflective type material, the energy from the fields reflect away from the target device, which prevents EMI/RFI waves from entering the device. As previously stated, for strong fields, multiple layers of reflective type shielding will need to be utilised.

Conclusion

78134088 application field and working principle of RFI and EMI Shielding and Absorbing materials is divided into absorptive type and reflective type, which is used to reflect the interference from EMI/RFI waves away from the target device or absorb the EMI/RFI waves into tiny currents. Both types of materials work to stop or reduce the possibility of interference between two or more electronic devices.
