title: One-Dimensional Non-Uniform Dielectric Structure as Tunable Resonator
abstract: The paper presents research on the composite dielectric resonators. This type of resonator consists of dielectric parts, which can move with respect to each other using an external actuator. The air discontinuity between dielectric parts perturbs the electromagnetic field of the resonator and as a result, shifts resonance frequency. As an analytical solution for this kind of structure does not exist, most practical techniques resort to approximate numerical solutions. The electromagnetic field p
