DOSIMETRIC USE OF SCHOTTKY DIODES
Authors not listed
The paper analyzes Schottky diodes for use in electric and magnetic field probes for dosimetric measurements.
Plain English Summary
Researchers examined the basic characteristics of microwave diodes including physical mechanisms and equivalent microwave circuits for dosimetric probe applications. Analytic expressions were developed that reveal linear, square-law, and other operating regions of the diodes. The effects of load resistance, bias current, and temperature on diode performance were explored. The analysis was applied to evaluate an E-field probe model designed for dosimetric use, comparing measurements with theory. Practical limitations on such probes were discussed and means of selecting diode parameters for maximum probe performance were presented.
Why This Matters
In biological research, electrical and magnetic field probes complement thermographic and thermometric measurement techniques to quantify both external and internal fields. Microwave diodes have been the overwhelming detector of choice due to their small size, ruggedness, and high impedance, yet their performance characteristics and limitations had been little analyzed for this application. The analysis was applied in an example showing computations for a diode probe designed and employed for dosimetric use, with performance explained in terms of the model and a comparison of actual and predicted values presented. A general discussion of dosimetric diode probes suggests ways to use diode characteristics to maximize probe performance and predict limitations in this measurement approach.
