The possibility of perfect (i.e. non-reflective) tunneling of microwave radiation through planar structures containing layers with negative material parameters is investigated. A symmetric trilayer is considered, including two ferrite layers, which are magnetized by an external field. The conditions of perfect tunneling are obtained analytically using the transfer matrix method. By the numerical solution of the obtained equations, the positions of the highest transmission peaks in the spectrum of the structure are determined. The controllability of the transmission spectra due to the external magnetic field is shown.
