电磁仿真软件用于模拟汤姆逊- csf公司先前设计的2-15 GHz液晶微带移相器的特性。在对计算结果进行实验验证后，将该软件应用于一种新型30-40 GHz多层微带移相器的建模中，该移相器的有效介质是插在固体介质衬底之间的液晶。在4.35厘米长的线路上进行的10至40 GHz的测量与理论预测非常吻合。以商用液晶（bhd - e44）和二氧化硅为衬底的结构在37 GHz下的最大实验相移为219.3°（约50°/ cm）。
Electromagnetic simulation software is used for modeling the properties of a 2–15 GHz liquid crystal microstrip phase shifter previously designed at Thomson-CSF. After experimental validation of the computed results, the software is applied to the modeling of a new 30–40 GHz multilayer microstrip phase shifter, where the active medium is a liquid crystal inserted between solid dielectric substrates. Measurements carried out at between 10 and 40 GHz on 4.35 cm long lines are in good agreement with theoretical predictions. A maximum experimental phase shift of 219.3° at 37 GHz (about 50°/ cm) was observed for a structure with a commercial liquid crystal (BDH-E44) and silica substrates.
