Terahertz Radiation Fundamentals
Terahertz (THz) radiation, often called T-rays, occupies a unique position in the electromagnetic spectrum, bridging the gap between microwaves and infrared light. It has distinct properties that make it valuable for various applications.
Key Constants:
- Speed of Light (c): 2.99792458 × 108 m/s
- Planck's Constant (h): 6.62607015 × 10-34 J·s
- Electron Charge (e): 1.602176634 × 10-19 C (for eV conversion)
Conversion Formulas:
- Frequency (f) ↔ Wavelength (λ): c = f × λ
- Photon Energy (E) ↔ Frequency (f): E = hf
- Photon Energy (E) ↔ Wavelength (λ): E = hc / λ

Frequently Asked Questions
What is Terahertz (THz) radiation?
Terahertz (THz) radiation, also known as T-rays, refers to electromagnetic waves with frequencies between 0.1 THz and 10 THz. This region lies between microwaves and infrared light in the electromagnetic spectrum.
What are the unique properties of THz radiation?
THz radiation can penetrate many non-conductive materials like plastics, clothing, and paper, similar to microwaves, but unlike X-rays, it is non-ionizing. It also has strong absorption by water, which makes it useful for detecting moisture but challenging for atmospheric transmission.
What are the applications of THz technology?
THz technology has emerging applications in security screening (e.g., airport scanners), medical imaging (non-invasive diagnostics), quality control in manufacturing, spectroscopy (identifying materials), and high-speed wireless communication.
