Laird Technologies Launches Interactive EMI Shielding Effectiveness Calculator

Online Interactive Calculator Provides Instantaneous Shielding Effectiveness Computation of Shielding Materials


St. Louis, Missouri, USA – August 18, 2011 – Laird Technologies, Inc., a global leader in the design and supply of customized performance-critical components and systems for advanced electronics and wireless products, today announced that it has launched the Laird Technologies Shielding Effectiveness Calculator. The online application is available for free on the Laird Technologies Website.

Drawing from an available library of standard shielding materials, the Laird Technologies Shielding Effectiveness Calculator estimates shielding effectiveness. 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.

As information is entered, the calculator computes shielding effectiveness, and 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,” said 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.”

As an industry-leading EMI solutions provider, Laird Technologies provides innovative board-level solutions with every available material and form factor for high-tech industries and applications around the world. For more information, please logon to
