Some Effects of Geologic Structure on Radio Rreception


Howell, Benjamin Franklin (1942) Some Effects of Geologic Structure on Radio Rreception. Master's thesis, California Institute of Technology. doi:10.7907/H017-TG68.


Radio fields at standard broadcast frequencies were examined over faults to determine how the geologic conditions affected the fields. The fields in rugged and densely inhabited areas were found to be too irregular to yield understandable patterns. Very small variations in the direction of the field were suggested but not proven over the San Jacinto Fault in the San Jacinto Valley. No variations in intensity were found over the San Andreas Fault east of Palm Springs, but variations were observed at some places over the Piedmont Fault in New Jersey. Such variations might be due to the higher conductivity of the fault plane, or to the addition of waves reflected and refracted by the fault surface. Weak areas near San Bernardino were noted, but could not be correlated with faults. Further studies, especially directional, with more delicate apparatus than used in this survey are needed.
