Abstract

Abstract Overview

The study focuses on the use of 0.30 THz radiation, commonly used in industrial, security applications, and wireless communication. The absorption capabilities of soft tissues at this frequency highlight a crucial aspect of its interaction with human anatomy.

Key Findings

• Absorption by soft tissue at 0.30 THz is high, allowing only 0.2 to 0.4 mm of effective energetic penetration.
• The study uses computational simulations to explore how 0.30 THz radiation could diffuse through the ear canal, potentially affecting the tympanic membrane.
• Simulations indicate substantial protection by outer ear structures, with very minimal power flux density reaching the central region of the tympanic membrane when directed at various angles.

Conclusion

The research highlights the protective qualities of outer ear structures against 0.30 THz radiation but also raises concerns about the sensitivity of the tympanic membrane to such radiation. The insights obtained advocate for in-vivo assessments to potentially reevaluate current radiation safety standards and design guidelines for devices emitting 0.30 THz radiation.
