abstract

  • Magnetic photonic assemblies (MPAs) are studied for applications in antennas for GHz frequencies with much improved coupling and gain. The proposed MPA designs contain two types of layers: low loss anisotropic dielectric "A" layers and low loss ferromagnetic "F" layers. This paper shows how effective "A" layers can be manufactured by perpendicularly slicing thin layers from ceramic laminates (CLs). The laminates consist of alternating sheets of two different ceramics with largely different permittivity and low dielectric losses. The CLs were assembled and shaped from commercially available ceramic α-Al2O3 and Nd-doped BaTiO 3 substrates. Their high-frequency dielectric properties were obtained with microwave cavity measurements and finite-element-modeling (FEM) assisted analysis. The measured anisotropic dielectric constants were in agreement with mean field predictions. Dielectric losses were higher than the reported minimum values of constituent materials, primarily due to extrinsic factors.
