The Laird Technologies Electromagnetic Interference (EMI) Shielding Effectiveness Calculator provides instantaneous shielding effectiveness computation of shielding materials for free on the company's website (www.lairdtech.com). Suitable for all markets that use shielding materials, the interactive online calculator draws from an available library of standard shielding materials. Users can also simulate their own material by entering the material’s relative conductivity and relative permeability. Parameters for the shielding computation are entered through a simple-to-use interface. They include material thickness, relative permeability, relative conductivity, and a user-defined pattern of apertures. Other selectable parameters are offered as well, such as aperture aspect ratio, frequency range, and emitter location and distance. Multiple measurement units are also supported.
