A free rigid waveguide slide rule app for mobile devices is now available for download to iOS and Android devices. Enables design engineers to input their own waveguide rectangular designations to perform complex conversions and determine operating parameters. By entering WR dimensions, a user can generate material specifications, including recommended operating frequency rate (GHz), flange type, and waveguide dimensions (in.).
