研究目的
Investigating the effect of increasing the resistance of a THz bowtie antenna-coupled microbolometer on its power efficiency performance.
研究成果
The designed THz bowtie antenna-coupled microbolometer shows that the maximum surface current is obtained at the resonant frequency of the antenna. Dissipated power and efficiencies increase as the bolometer resistance increases. Further analysis is needed to be carried out with greater resistance to obtain and predict maximum efficiency.
研究不足
The study is limited to simulation results and does not include physical experimentation. Further analysis is needed with greater resistance to obtain and predict maximum efficiency. A return loss analysis of the microbolometer can also be considered for further research.
1：Experimental Design and Method Selection:
The study involves designing and simulating a THz bowtie antenna-coupled microbolometer for the 1 THz frequency band using CST Microwave Studio. The simulation includes a surface current analysis to understand the effect of the microbolometer's resistance on power efficiency.
2：Sample Selection and Data Sources:
The design is expected to work at resonant frequencies around 1 THz, with the input impedance of the antenna determined at 50 ?.
3：List of Experimental Equipment and Materials:
CST Microwave Studio software is used for simulation. The microbolometer is made of a conductive bar designed at the center point between the bowtie triangles.
4：Experimental Procedures and Operational Workflow:
The simulation is conducted by illuminating the proposed design with a linearly polarized electric plane wave of 1 V/m and analyzing the obtained surface current in the microbolometer surface.
5：Data Analysis Methods:
The surface current and dissipated power effect are analyzed, and a transmission line model is created from the proposed design to further analyze the results.
