A 249-GHz Impedance-Tunable Waveguide Transition Using a Microactuator and Flexible Conductive Membrane by Chao Qi, Sangyeop Lee, Takeshi Yoshida, Tadahiko Shinshi

“…However, as frequencies increase and wavelengths shorten, mechanical tolerances during integration can significantly impact performance (reflection, transmission, etc.), necessitating effective compensation mechanisms. In this paper, we verify the performance variations caused by mechanical tolerances in transmission-line-to-waveguide transitions, which integrate chips, substrates, and waveguides to transmit signals generated by the chip or receive signals from external sources. …”

Impact of Aggregate Characteristics on Frictional Performance of Asphalt-Based High Friction Surface Treatments by Alireza Roshan, Magdy Abdelrahman

“…While Epoxy-based HFSTs are widely applied, they present limitations such as compatibility issues with existing pavements, high installation and removal costs, and durability concerns tied to substrate quality. As an alternative to traditional Epoxy-based HFSTs, this study investigated the effects of aggregate gradation as designated by agencies on the performance of asphalt-based HFST. …”
