What is a Shielding Effectiveness Calculator?
A shielding effectiveness calculator is a tool that calculates the amount of electromagnetic radiation that is blocked by various shielding materials. The calculator considers the properties of the material, the size and shape of the shield, the frequency of the radiation, and other factors. Using these inputs, the calculator generates a number that indicates how well the shield blocks radiation.
Why is Shielding Effectiveness Important?
Shielding effectiveness is important because it determines how well a device can protect against electromagnetic radiation. Unshielded devices are vulnerable to electromagnetic interference (EMI), which can cause malfunctions and data loss. EMI can come from a variety of sources, including natural phenomena like lightning and solar flares, as well as man-made sources like radios, TVs, and digital devices.
How is Shielding Effectiveness Calculated?
The shielding effectiveness of a material is determined by measuring the amount of radiation that is blocked by the material. This measurement is expressed in decibels (dB), which is a logarithmic scale. To calculate shielding effectiveness, the dB value of the unshielded radiation is subtracted from the dB value of the shielded radiation.
Factors That Affect Shielding Effectiveness
The effectiveness of a shield depends on several factors, including:
- The properties of the shield material: High conductivity materials like copper and aluminum are most effective at blocking electromagnetic radiation.

- The shape of the shield: Shapes that minimize gaps and seams will perform the best.
- The frequency of the radiation: Different materials are more effective at blocking certain frequencies than others.
- The quality of the grounding: Any EMI that is not absorbed by the shield must be dissipated through the grounding system for the device to function properly.
How Can a Shielding Effectiveness Calculator Benefit Your Project?
Using a shielding effectiveness calculator can lead to several benefits, including:
- Improved performance of your shielding system.
- Reduced costs and testing time.
- Increased confidence in meeting regulatory requirements.
- Optimized shielding design based on specific project requirements.
