Proceedings of the IRE
special issues are still available Each issue of proceedings of the ire
is the result of the most advanced thinking in the field of radio-electronics. Based on exacting research, and written by men who are foremost in their specialty, these issues are invaluable works of reference. This is also material not available from any other source. As the official publication of The Institute of Radio Engineers, PROCEEDINGS presents the years-ahead ideas on which new advances are based. These history-making issues, originally over-printed for reserves are rapidly
being exhausted and will not be reprinted.
YOU CAN STILL GET:
VERY LOW FREQUENCY* June, 1957 — New research in the very low frequency band, below 30 kc, opens up greater portions of the radio spectrum for communication purposes. VLF has many new and important uses. A reference work
you'll need for years.
SINGLE SIDEBAND, December, 1956 — A round-up of recent technical discoveries as presented by the Joint Technical Advisory Committee through its sub committee on Single Sideband techniques. This special study for the FCC points
up the many advantages of single sideband.
FER RITES, October, 1956 — This new group of solid state materials outmodes the intermittent "pulse" system of World War II radar. The ferrites allow simultaneous sending and receiving on a single microwave antenna; as well as fullpower transmission in microwave ranges with reduced power loss and interference.
SOLID STATE ELECTRONICS, December, 1955 — This issue heralds the arrival of a new epoch in radio electronics — the solid state electronics era. Defined and named with the birth of the transistor, this concerns the control and utilization of the electric magnetic and photic properties of solids. There are now whole new classes of electronic devices due to discoveries in this field.
SCATTER PROPAGATION, October, 1955 — Here's radio history in the making. This issue presents practical application of a new principle in the fields of broadcasting and electronics. Thirty-five papers lay the foundation of a new means of communicating over long distances.
