Abstract Detecting unsafe levels of chemical gases and vapors is essential in improving and maintaining Printed Color Hat Misc a healthy environment for all to enjoy.Propylene glycol is a colorless, synthetic gas commonly used in medications, fragrances, and cosmetics.It causes side effects such as headaches, lightheadedness, nausea, and fainting.

So, monitoring of propylene glycol is critically vital.This study uses a defected photonic crystal as a propylene glycol THz sensor.Due to the high absorption of propylene glycol, the intensity of the resonant Shovel confined mode is very small.

As a result, the performance of the designed sensor seems unsatisfactory.We will use parity-time symmetry for the first time in THz to magnify the resonant confined mode to detect propylene glycol.The effect of microcavity thickness, incident angle, and gain/loss factor will be studied.

The optimized sensor recorded distinguished results compared to other studies for the detection of propylene glycol.
