"I believe in limited government, and the 20th century has been the century of government. The data is uniform. The government has failed at every single task it has set out to do, with the exception of waging war."
- Bart Kosko

Pressor Field  
  A force field that pressed against anything that encountered it.  

I later learned that the city sprawled out over 200 square kilometers, that you could take a subway to anyplace that was too far to walk. The ecology of Threshold was very carefully balanced and maintained so as to resemble the jungle outside with all the dangerous and uncomfortable elements eliminated. A powerful pressor field kept out large predators and such insect life as was not necessary for the health of the plants inside.
From The Forever War, by Joe Haldeman.
Published by Not Known in 1974

As far as I know, the first reference to such a field was the pressor beam from Gray Lensman, the 1942 novel by E.E. 'Doc' Smith.

A similar idea for a similar purpose is the sonabarrier from Frank Herbert's 1977 novel The Dosadi Experiment.
