WebApr 3, 2024 · Surfaces of semiconducting materials excited by femtosecond laser pulses emit electromagnetic waves in the terahertz (THz) frequency range, which by definition is the 0.1–10 THz region. The nature of terahertz radiation pulses is, in the majority of cases, explained by the appearance of ultrafast photocurrents. THz pulse duration is … WebJan 25, 2024 · Similarly, wave equation for magnetic field is given as. ∇ 2 H − μ ϵ δ 2 H δ t 2 − μ σ δ H δ t = 0. By comparing this Maxwell derived the relation for the velocity of electromagnetic waves and it was given as. v = 1 μ o μ r ϵ o ϵ r = 1 μ o ϵ o. 1 μ r ϵ r = c μ r ϵ r. c v = μ r ϵ r = n.
