The transmittance of electromagnetic waves, with normal incidence, in 1-D random extrinsic magnetized plasma photonic structures is studied numerically based on the transfer-matrix method. Here, the homogeneous magnetized plasma having a uniform density profile is considered. Continuing a previous study [IEEE T. Plasma Sci., vol. 47, no. 4, pp. 1726–1733, 2019], we investigate how the main photonic bandgap in an extrinsic magnetized plasma photonic structure changes when the positions of the layers in the entire structure are random. The numerical calculations show that a robust photonic bandgap can be realized up to a certain probability of occurrence. Also, we show that the proposed random multilayered structure can work as a robust tunable photonic lattice which can be controlled by the plasma parameters and the external magnetic field.
