Abstract
Superconducting heterodyne mixers have found widespread use
throughout the Millimeter- and Sub-millimeter wavelength range in
radio astronomy applications that need very high spectral
resolution. To extend their operating range into the Terahertz
region, which is opened up by new high altitude observatories,
airborne platforms or satellites, requires further development of
superconductor materials as well as progress in radio frequency (RF)
design and detector fabrication. This paper summarizes the basic
challenges in these areas.

| What is OpenURL? |
The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
