Computational Design of a Broadband In-Line Coaxial-to-Rectangular Waveguide Transition

open access: yesApplied Sciences, 2023
This Communication presents a computational design approach for a broadband in-line coaxial-to-rectangular waveguide transition having a 2.83:1 bandwidth. Existing designs have a bandwidth ranging from 1.36:1 to 2:1. The proposed transition consists of a

Generalized non-coaxial theory based on orthogonal decomposition of stress rate

open access: yesYantu gongcheng xuebao, 2021
In the traditional non-coaxial theories, linear assumption is usually made between non-coaxial plastic strain rate and non-coaxial stress rate, and they are always in the same direction, which is inconsistent with the real non-coaxial deformation ...
