Abstract
An improved Nicolson-Ross-Weir (NRW) transmission/reflection method with the algorithm of adapting propagation constant is proposed in this paper for the permittivity measurement of that material with arbitrary thickness. The basic principle of the NRW method is reviewed and verified first, and the proposed improved method and adaptive algorithm are introduced and simulated for verification using the coaxial line measurement system. Both 2.92 and 7.0 mm measurement systems are fabricated to verify our method by measuring four different materials. By comparing the measured results in existing art and those using the proposed method, as well as the uncertainty and error analyses, one can see that our proposed method has the capability of measuring the permittivity of those materials with arbitrary thickness with high accuracy and efficiency.
期刊介绍：
IET Science, Measurement & Technology publishes papers in science, engineering and technology underpinning electronic and electrical engineering, nanotechnology and medical instrumentation.The emphasis of the journal is on theory, simulation methodologies and measurement techniques.
The major themes of the journal are:
- electromagnetism including electromagnetic theory, computational electromagnetics and EMC
- properties and applications of dielectric, magnetic, magneto-optic, piezoelectric materials down to the nanometre scale
- measurement and instrumentation including sensors, actuators, medical instrumentation, fundamentals of measurement including measurement standards, uncertainty, dissemination and calibration
Applications are welcome for illustrative purposes but the novelty and originality should focus on the proposed new methods.
