Abstract The factors influencing the power-handling capability of antennas at high altitude are considered in this paper. The physical mechanism involved, including the roles of attachment, free… Expand
The Use of Ion Probes in Re-Entry Physics
- H. R. Bredfeldt, W. Scharfman, H. Guthart, T. Morita
- Physics
- 1 May 1965
Abstract : Classical (Langmuir) probe theory is reviewed and the conditions under which it is applicable to the re-entry physics problem identified. Some later developments in probe theory, which… Expand

Voltage breakdown characteristics of microwave antennas
- J. Chown, T. Morita, W. Scharfman
- Materials Science, Physics
- 1958
At low pressures, antennas are susceptible to voltage breakdown. In the case of missiles, for example, there are indications that very low power is sufficient to initiate and maintain breakdown.… Expand
Boundary-Layer Ion Density Profiles As Measured by
- H. R. Bredfeldt, W. Scharfman, H. Guthart, T. Morita
- Materials Science, Chemistry
- 2 March 1966
Ion-density profiles in boundary layers associated with supersonic flow of shock-heated air over a flat plate have been measured by cylindrical and flush-mounted electrostatic probes. A method of… Expand
Voltage Breakdown Characteristics of Microwave Antennas
- J. Chown, W. Scharfman, T. Morita
- Engineering
- Proceedings of the IRE
- 1958
The problem of voltage breakdown and its effects is discussed for a pulse antenna system. Voltage breakdown occurs at power levels when the pressure is reduced. The minimum breakdown potential occurs… Expand
Breakdown limitations on the transmission of microwave power through the atmosphere
- W. Scharfman, W. Taylor, T. Morita
- Materials Science
- 1 November 1964
One of the limiting factors in the transmission of the increasingly large amounts of microwave power available is voltage breakdown of the atmosphere. Almost all of the published work dealing with… Expand
Focused Microwave Technique for Measurement of the Ionization Rate and Collision Frequency
- W. Scharfman, T. Morita
- Physics
- 1 July 1964
A technique for the measurement of ionization rate and collision frequency in gases uses high‐powered focused microwaves. By using short pulses and focusing the energy into a small spot within a… Expand
RESEARCH STUDY OF MICROWAVE BREAKDOWN OF AIR AT HIGH ALTITUDES
- W. Scharfman, W. Taylor, T. Morita
- Chemistry
- 1 August 1962
Abstract : Almost all of the published work dealing with voltage breakdown at microwave frequencies was concerned with breakdown in the presence of surfaces to which articles can diffuse. Recent… Expand
