Hypothesis
Can a Photonic Crystal Fiber (PCF) sensor effectively differentiate between methanol and ethanol in the THz range?
Conclusion
The PCF sensor demonstrates high sensitivity and low material loss, making it effective for distinguishing between methanol and ethanol.
Supporting Evidence
- The sensor achieved maximum relative sensitivities of 95.72% for methanol and 97.55% for ethanol.
- It operates in the 2.2 to 3.2 THz range with low Effective Material Loss values.
- The design enhances detection accuracy and safety monitoring in industrial applications.
Takeaway
This study created a special sensor that can tell the difference between two types of alcohol, methanol and ethanol, which is really important for safety.
Methodology
The sensor was developed using COMSOL Multiphysics to simulate its performance in detecting alcohols based on their refractive indices.
Limitations
Challenges in precise fabrication and maintaining consistent calibration in varying environmental conditions may affect sensor performance.
