AIRCRAFT RADAR MEASUREMENTS IN THE NEAR FIELD

Richard A. Tell, Norbert N. Hankin, David E. Janes, Jr. · 1976

Researchers measured microwave exposure levels near parked commercial aircraft from weather radar installed in the nose of the aircraft on five aircraft with three radar types. Measurements were made on stationary antennas and average values of power density were calculated taking into account antenna rotation. With the antennas rotating, only one system produced a level in excess of the current OSHA-ANSI standard of 10 milliwatts per square centimeter (mW/cm2). For rotating antennas the power density decreased to less than 1 mW/cm2 at distances greater than 3.5 m (11.5 ft.) for all systems measured. The measured values agree well with values calculated from a model employing near-field gain correction factors.

An Investigation of the Use of Microwave Radiation for Pulmonary Diagnostics

P. C. PEDERSEN, C. C. JOHNSON, C. H. DURNEY, D. G. BRAGG · 1976

Researchers used a 13 cm by 13 cm applicator at 915 MHz with power levels of 50 to 100 microwatts to measure microwave reflection during human respiration. Deep breathing produced maximum amplitude and phase changes of about 1 dB and 5 degrees with the applicator on the chest and 2 dB and 10 degrees on the back. In a dog with artificially induced edema, baseline amplitude shifts followed edema progression up to 15 times normal respiratory changes, while only a small phase shift occurred. The authors concluded the technique may allow qualitative monitoring of lung water changes but not quantitative determinations or discrimination between intra- and extravascular fluid.

A review of microwaves for food processing

A. J. H. Sale · 1976

Microwave heating alone has led to few commercial successes but combined with conventional heating has greater potential and several successful processes. Successful applications include pasta drying using a combination of microwave heating with hot air that reduces drying time from about 10 hours to about half an hour, and doughnut proofing that reduces proofing time from 30-40 minutes to 4 minutes with more than twenty units installed.

A simple way to obtain a low-cost high sensitivity detector is to use an active device, especially a transistor oscillator, coupled to an antenna. The detector operates in a frequency-selective mode at low power densities and can switch to a non-selective mode at higher densities by adjusting the antenna coupling.

Light-induced fast conformational change in all-trans-retinal at low temperature

S. Georghiou · 1976

Researchers measured nanosecond fluorescence of all-trans-retinal in a non-polar matrix at 100 K. The fluorescence spectrum broadened from 113 nm to 127 nm full width at half maximum within nanoseconds after excitation, while the spectral maximum and long-wavelength portion remained unchanged.

Pacemakers and External Interference

Elmqvist H · 1976

The paper describes interference mechanisms, the most common sources of external electromagnetic interference, and their influence on different types of pacemakers. It identifies three ways external electromagnetic interference can influence pacemaker function. Remote sources include microwave ovens, radar installations, and radio-transmitters, while direct contact sources include defibrillation, diathermy, short-wave treatment equipment, and household appliances with poor insulation. A survey of over 2200 patients found only 10 cases of interference with no serious consequences. Modern pacemakers use an interference filter that discriminates signals by repetition rate and a metal encapsulation that reduces microwave effects.

Microwave Auditory Effect—A Comparison of Some Possible Transduction Mechanisms

James C. Lin · 1976

The study compares radiation pressure, restrictive force, and rapid thermal expansion as possible transduction mechanisms for the microwave auditory effect. At a peak absorbed power density of 2400 watt/m² for 2450 MHz radiation, the computed maximum stress is approximately 0.02 Newtons/m², which is above the bone-conduction hearing threshold.

Technical Data Models 1036 and 1037 Digital Power Meter

Pacific Measurements Inc. · 1976

Model 1036 measures from -40 dBm to +10 dBm in a single range while Model 1037 measures from -30 dBm to +20 dBm. The instruments achieve rated accuracy of +0.02 dB on the upper 30 dB and +0.04 dB on the lower 20 dB of the power range. A self-check feature uses a front-panel calibrator providing 10 milliwatts accurate within +0.06 dB at 30 MHz. The detectors are protected against overloads up to 10 times full-scale rating and are field-repairable.
