S 교정 방법11 3개의 기준 물질이 삽입되고 짧은 종단 조건이 없는 동축 급전형 차단 원형 도파관용 물질의 전면에서 액체의 유전체 측정을 위한 예비 단계로 제안되었습니다. S의 지그 교정 방정식11 이들 기준물질을 이용하여 먼저 정의하고, 반사상수(모드매칭(MM) 기법을 이용하여 0.50, 1.5, 3.0 GHz 주파수에서 계산)을 지그의 샘플 액체를 가정하여 등가 회로. S의 정확도11 제안된 방법으로 측정한 결과를 검증하였다. 에스11 시료 물질의 전면에 대해서도 교정 후 지그 내 다양한 액체를 사용하여 측정하였고, S의 비교를 바탕으로 액체의 유전율을 역문제로 추정하였다.11 측정된 S를 사용하여 MM 기술을 통해 EM 분석을 사용하여 분석 모델로부터 계산11 위에서 설명한 값입니다. 제안된 S의 효율성11 S 이후에 추정된 유전율과의 비교를 통해 교정방법을 검증함11 SOM(Short, Open, Reference Material) 교정 및 이와 유사하며 결과는 각 방법과 호의적으로 일치하는 것으로 나타났습니다.

Abstract: A method for the calibration of S11 at the front surface of a material for a coaxial-feed type cut-off circular waveguide with three reference materials inserted and no short termination condition was proposed as a preliminary step for dielectric measurement in liquids. The equations for jig calibration of S11 with these reference materials were first defined, and the electrostatic capacitance for the analytical model unique to the jig was quantified by substituting the reflection constant (calculated at frequencies of 0.50, 1.5 and 3.0 GHz using the mode-matching (MM) technique) into the equivalent circuit, assuming the sample liquid in the jig. The accuracy of S11 measured using the proposed method was then verified. S11 for the front surface of the sample material was also measured with various liquids in the jig after calibration, and the dielectric constants of the liquids were estimated as an inverse problem based on comparison of S11 calculated from an analytical model using EM analysis via the MM technique with the measured S11 values described above. The effectiveness of the proposed S11 calibration method was verified by comparison with dielectric constants estimated after S11 SOM (short, open and reference material) calibration and similar, with results showing favorable agreement with each method.
