Split-Block Waveguide Polarization Twist for 220 to 325 GHz
hot!
|
|
Date added: 03/01/2008 |
|
The new technology reported here allows waveguide polarization twists to be integrated directly into standard split-block waveguide circuits using common fabrication methods including end-milling or silicon deep reactive ion etching (DRIE.) The result is scalable
to circuits operating at frequencies of at least 5 THz. |

Solid-State High-Temperature Power Cells
|
|
Date added: 05/01/2008 |
|
All-solid-state electrochemical power cells have been fabricated and tested in a continuing effort to develop batteries for instruments for use in hot environments. Batteries of this type are needed for exploration of Venus, and could be used on Earth for such applications as measuring physical and chemical conditions in geothermal wells and oil wells, processing furnaces, and combustion engines. |
