Abstract: This letter proposes an angle-multiplexed multifocal method for designing a 2-D beam-scanning transmitarray (TA). The angle-multiplexed method is commonly used to generate orbital angular ...
Abstract: The instability of the sheet electron beam (SEB) is an essential factor for limiting the power of the SEB traveling wave tube (TWT). To solve this issue, this article proposes a method to ...
A new study demonstrates how near-surface-mounted (NSM) reinforcement can effectively mitigate the shear loss caused by vertical holes in concrete beams, providing safer and more flexible design ...
