The utility of the magnetically insulated transmission line oscillator (MILO) as a high power microwave source depends on how efficiently power can be extracted from it. We have designed a slow-wave stepped transformer for the purpose of axially extr

Experiments with 400-MHz and 13.3-GHz radar scatterometers indicate that these all-weather remote sensors provide some information which may be used to discriminate between some types of sea-ice categories. Using 12 incidence angles, first-year and m

Measurements of the ground wave field intensity were made along radial paths from a low-frequency transmitter in Rapid City, S. Dak. Ground wave attenuation curves for different conductivities are compared with the measured data. Millington's mixed p

Results of antenna pattern measurements of a notch antenna are presented for variable notch lengths and different modes of notch excitation. The notch is an open slot normal to the edge of a 12° metallic wedge. Antenna patterns of the E θ component

Radio ground-wave propagation in the Arctic Ocean occurs over mixed paths. The mixed paths include layered or homogeneous sea ice and sea water. Amplitude and phase variations occurring as "dropoff" or "recovery" effects at the ice-sea-water boundari

This paper presents a simple method for the determination of the attenuation encountered by a VHF signal as it passes through a flame or the exhaust trail produced by a flame. The measurements are made of the VSWR and the shift of the minimum electri
