Guided Wave Propagation In Cylindrical Domains With Non-Orthogonal Sets Of Normal Modes, Herbert H. Snyder
Guided Wave Propagation In Cylindrical Domains With Non-Orthogonal Sets Of Normal Modes, Herbert H. Snyder
Proceedings of the Iowa Academy of Science
Guided wave propagation is studied for the interior of circularly cylindrical domains; on the (cylindrical) boundary the ratios E2/Hφ and H2/Eφ are assigned functions of frequency and position, called surface impedances. Even in the case where the impedances are independent of position on the wall, the normal modes of propagation (expressed in terms of certain Bessel functions) do not form an orthogonal set on sections of the guide normal to the propagation direction. It follows that mode relative amplitudes cannot be determined by a Fourier-Bessel expansion of steady-state fields given on an input plane. To determine …

Army Junior Science, Engineering And Humanities Symposium, Anne Marie Herman
Iowa Science Teachers Journal
Do a research project, explore it, put time, hard work, and study into it and numerous rewards come about. Especially for six Iowa students selected to go to the National Junior Science and Humanities Symposium held at West Point Academy, New York, May 9-12, 1973. The six students who represented Iowa at the Symposium were: Paul Sugg, Knoxville Sr. High School; Kevin Baker, Spirit Lake High School; Joe Depenbusch, Emmetsburg Comm. High School; Anne Marie Herman, Sigourney Comm. High School; Bruce Luxon, West Waterloo High School; and Gordon Waite, Maquoketa Senior High School.

Secondary Teacher Education: Where We Are Going At The University Of Iowa, Robert E. Yager
Secondary Teacher Education: Where We Are Going At The University Of Iowa, Robert E. Yager
Iowa Science Teachers Journal
In September of 1970 a grant was awarded by the National Science Foundation to the Science Education Center at the University of Iowa for the development of pre-service programs for teachers of secondary school science. The program was called Iowa-UPSTEP, (Undergraduate Pre-Service Teacher Education Program). The rationale for this program and a report of its progress is a response to "Where We Are Going" at the University of Iowa.
