Laird Technologies launches online, interactive EMI shielding effectiveness

ST. LOUIS, Mo., 27 Aug. 2011. Laird Technologies Inc., provider of customized performance-critical components and systems for advanced electronics and wireless products, has launched the Laird Technologies Shielding Effectiveness Calculator. The free, online application estimates shielding effectiveness based either on standard shielding materials in an existing library or user-defined relative conductivity and relative permeability material parameters. Users can enter parameters, such as material thickness, relative permeability, relative conductivity, and a user-defined pattern of apertures. Other selectable parameters are offered, such as aperture aspect ratio, frequency range, and emitter location and distance. Multiple measurement units are also supported.

ST. LOUIS, Mo., 27 Aug. 2011. Laird Technologies Inc., provider of customized performance-critical components and systems for advanced electronics and wireless products, has launched the Laird Technologies Shielding Effectiveness Calculator. The free, online application estimates shielding effectiveness based either on standard shielding materials in an existing library or user-defined relative conductivity and relative permeability material parameters. Users can enter parameters, such as material thickness, relative permeability, relative conductivity, and a user-defined pattern of apertures. Other selectable parameters are offered, such as aperture aspect ratio, frequency range, and emitter location and distance. Multiple measurement units are also supported.

The calculator computes shielding effectiveness based on the information entered. If there are apertures, it plots their pattern. It also plots shielding effectiveness over the selected frequency range.

“The Laird Technologies Shielding Effectiveness Calculator addresses the need to provide shielding effectiveness technical information in a very quick manner for Laird Technologies customers,” says Gary Fenical, Laird Technologies EMC technical representative and NARTE-certified EMC & ESD engineer. “Easy and intuitive, and ideal for all markets that use shielding materials, it provides shielding computations instantaneously.”
