Description

Thomas J. Countis established Countis Industries in 1964 located in San Luis Obispo, CA, where he developed a line of microwave spinel ferrite materials that were mainly sold to US firms working in the defense sector. Mr. Countis graduated from the University of Colorado in 1949 with a degree in Engineering Physics and worked for 15 years in magnetic material development before starting his own company. Mr. Countis gained knowledge of microwave ferrites from his experience working at Collins Radio Company from 1953 to 1957 and Hughes Aircraft Company from 1958 to 1963. He was instrumental in setting up and producing the first ferrite materials used in microwave devices. In 1977 Mr. Countis worked with his son, Thomas M. Countis, in developing garnet ferrite materials and a line of microwave dielectric materials. As a graduate from Purdue University with a Masters Degree in Physics, Thomas M. Countis worked in the aerospace industry for several years before joining with Countis Industries. In 1978, Thomas M. Countis established Countis Laboratories as a separate business that focused on the production of garnet ferrite and dielectric materials. He leased a 2,500 square foot space to begin production in San Luis Obispo. Continuing research resulted in the development of very narrow line width calcium-vanadium garnets, as well as a unique zirconium substituted material. These were supplied to the microwave market in the early 1980's. These materials were used extensively in...
