Laird Technologies, Inc. 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 ?materialís relative conductivity and relative permeability.
Parameters for the shielding computation 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.
