1. Terahertz wave physics

1.1 Terahertz electromagnetic waves

It is now accepted by the entire scientific community that the range of terahertz electromagnetic waves typically extends between frequencies 0.1 and 10 THz. Let's recall the definitions of the energy E of a photon and the resulting relationships between frequency ν and wavelength λ :

E = hν = ℏ ω = \frac{hc}{λ} = k_{B} T \Leftrightarrow ν = \frac{ω}{2}
