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 ?material’s 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.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
