Advanced Terahertz Sensing of Liquid Petrochemicals: Pentagonal‐Core Photonic Crystal Fiber Design and Performance

Advanced Photonics Research, Volume 7, Issue 7, July 2026.
A hybrid‐structured pentagonal‐core photonic crystal fiber sensor operating in the terahertz regime is proposed for fuel adulteration detection. Numerical analysis using the finite element method in COMSOL shows optimal performance at 2 THz, achieving high relative sensitivity (up to 98.20%) with ultralow confinement loss (~10−¹³ dB/m). The design also
