    • Strictly speaking, the representation of external field as the second time derivative of an oscillating dipole is valid only for a fixed point dipole element. In fact, the treatments of terahertz emitters based on nonequilibrium carriers transport (ambipolar diffusion or drift) require the use of full set of Maxwell and transport equations with the correct set of boundary conditions. It is clear that replacement of this detailed analysis with a point dipole or current source is inadequate in the sense of quantitative analysis.

    • In general case the total current is distinguished as polarization current associated with bound charges and conduction current related to motion of free charges. This distinction can strictly be made only for static fields and becomes meaningless for time-dependent high-frequency fields. Therefore, the expression for current can be written in two equivalent forms, J (ω) = (Iω) ε0 χ̂eff (ω) E (ω) and J (ω) = σ̂eff (ω) E (ω), where χ̂eff (ω) = χ̂ (ω) - I σ̂ (ω) ε0 ω, σ̂ eff (ω) = σ̂ (ω) +Iω ε0 χ̂ (ω), and σ̂ eff (ω) = (Iω) ε0 χ̂ eff (ω). High-frequency current J (ω) can be treated as transverse polarization charge wave in plasma with χ̂ eff (ω) = χ̂ (ω) - I σ̂ (ω) ε0 ω.
