“…18,68 In this section, we will perform the numerical analysis of the TB state in PID plasma using the plasma parameters that are typical of Earth's ionosphere in the E-region where nn = 10 11 cm −3 , ni = 10 5 cm −3 , Z d n d ≃ 0.7ni, ne ≃ 0.3ni, B 0 = 0.5 G, mi = m NO + = 5.5 × 10 4 me, and mn ≈ mi. 69 In the relaxed state, the eigenvalues, which are functions of plasma parameters such as Beltrami parameters, species densities, masses, etc., preserve all the information about the nature and size of the relaxed state structures. Hence, we start by investigating how the Beltrami parameters affect the TB structures while keeping all the other plasma parameters the same.…”
