oratories, 1930-. Dr. Friis, Director of Research in High Frecjueney and 

 Electronics, has made important contributions on ship-to-shore radio 

 reception, short-wave studies, radio transmission (inchiding methods of 

 measuring signals and noise), a receiving system for reducing selective 

 fading and noise interference, microwave receivers and measuring equip- 

 ment, and radar eciuipment. He has published numerous technical 

 papers and is co-author of a book on the theory and practice of antennas.
