When a fiber‐optic thermometer is placed in a microwave field to measure temperature, there will be energy loss due to electromagnetic interaction, which will certainly bring error in the measured temperature, within the sensor. In this article we have simplified the sensor to a finite‐length cylinder, and calculated the energy loss and temperature error. In addition, the measurement error of temperature is studied for a practical thermometer transducer fiber‐optic sensor placed in a microwave field. © 1995 John Wiley & Sons, Inc.
