Kaedah untuk penentukuran S11 pada permukaan hadapan bahan untuk pandu gelombang bulat potong jenis suapan sepaksi dengan tiga bahan rujukan dimasukkan dan tiada syarat penamatan pendek dicadangkan sebagai langkah awal untuk pengukuran dielektrik dalam cecair. Persamaan untuk penentukuran jig S11 dengan bahan rujukan ini mula-mula ditakrifkan, dan kemuatan elektrostatik untuk model analitik yang unik kepada jig dikira dengan menggantikan pemalar pantulan (dikira pada frekuensi 0.50, 1.5 dan 3.0 GHz menggunakan teknik padanan mod (MM)) ke dalam litar setara, dengan mengandaikan cecair sampel dalam jig. Ketepatan S11 diukur menggunakan kaedah yang dicadangkan kemudiannya disahkan. S11 untuk permukaan hadapan bahan sampel juga diukur dengan pelbagai cecair dalam jig selepas penentukuran, dan pemalar dielektrik cecair dianggarkan sebagai masalah songsang berdasarkan perbandingan S11 dikira daripada model analitik menggunakan analisis EM melalui teknik MM dengan ukuran S11 nilai yang diterangkan di atas. Keberkesanan cadangan S11 kaedah penentukuran telah disahkan dengan perbandingan dengan pemalar dielektrik yang dianggarkan selepas S11 Penentukuran SOM (bahan pendek, terbuka dan rujukan) dan seumpamanya, dengan keputusan menunjukkan persetujuan yang menggalakkan dengan setiap kaedah.

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.
