spectrum

Rice University's Argos Network will use base stations with more than 100 antennas apiece to share spectrum by beaming information directly to many users simultaneously on the same frequency.

chip

This silicon-germanium chip converts a digital trigger to a 5-picosecond pulse of radiation with a frequency spectrum exceeding 1 terahertz. The chip supports a repetition rate up to 10 gigahertz, provides beam-steering capability and contains a two-by-four array of transmitters with antennas that can each be independently programmed with resolution steps of 300 femtoseconds.

simulation

The awards continue NSF's ongoing investment in radio spectrum research, which over the past five years has supported more than 140 awards through an investment of over $60 million. Shown here are full-wave electromagnetic simulation results of a lens antenna.
