Temperature Stabilization of Electromagnetic Wave Phase Velocity in Rectangular Waveguide with Layered Nanocomposite Ferroelectric Film
Abstract
A solution is obtained for propagation constant of electromagnetic wave fundamental mode in straightangle waveguide with the cross section partially filled with multilayer nanocomposite ferroelectric film (MNESEP) on a dielectric substrate. The numerical model is based on the scalar form of the finite element method reduced to a homogeneous system of lin-ear algebraic equations with respect to nodal values of the wave scalar for one-dimensional approximation. The nanolayer dielectric properties are determined by barium concentration dependence in composition of BaxSr1-xTiO3 sol-id solution. A calculation program for several dozens of elements of partition along the wide wall of a rectangular waveguide is developed. The results of computer modeling for MNSEP with different number of layers and concentration dependences of barium are given, which allow to stabilize the propagation constant over a wide temperature range.
