In order to address the high-order mode (HOM) oscillation that may affect the stability of traveling wave tubes (TWTs), a new strategy called conformally loaded metasurface filter (MF) has been ...

Abstract: In this letter, we reported a gyrotron traveling wave tube (gyro-TWT) featured broadband and high power at the University Electronic Science and Technology of China (UESTC), which had ...

New York City began using pneumatic tubes in 1897. The original underground New York City tube system ran between the main post office building and station P, located in the Produce Exchange building.

We report a temperature dependent crystalline structure of spin-coated thin films of high molecular weight regioregular poly(3-hexylthiophene) (P3HT) (Mn ∼ 30000 g/mol) and its correlation with charge ...
