研究目的
To design a simple and compact polarization plane rotator that enables polarization conversion at two predetermined frequencies simultaneously.
研究成果
The study demonstrates the feasibility of designing a simple and compact polarization plane rotator that enables dual-frequency operation. The polarization rotation frequencies and their separation can be controlled by adjusting the dimensions and placements of the slots’ groups. The study also reveals that a rotator with equal slots can achieve dual-frequency operation, which is a novel finding compared to known designs.
研究不足
The study is limited to numerical simulations and does not include experimental validation. The effectiveness of the polarization conversion is dependent on the precise dimensions and placements of the slots’ groups.
1：Experimental Design and Method Selection:
The study uses a numerical approach based on the scattering matrix technique and the mode-matching technique (MMT) for waveguides with piece-wise boundaries.
2：Sample Selection and Data Sources:
The study examines a bilayered structure with eight slots for dual-frequency operation.
3：List of Experimental Equipment and Materials:
The study utilizes home-made software MWD-II developed in IRE NASU (Kharkov) for numerical calculations.
4：Experimental Procedures and Operational Workflow:
The study involves changing the dimensions and placements of the slots’ groups to control polarization rotation frequencies.
5：Data Analysis Methods:
The study analyzes the reflection and transmission characteristics of the incident mode into co-polarized and cross-polarized modes.
