摘要：

Nonlinear transmission lines (NLTLs) offer a robust, solid state solution for generating high power microwaves (HPM). NLTLs use nonlinear dielectric and/or magnetic materials whose permittivity and permeability, vary with voltage and current, respectively, to modulate a delivered pulse and generate RF. Materials such as barium strontium titanite (BST) and nickel zinc ferrites (NZF) are used for their nonlinear dielectric and magnetic properties, respectively. This study examines the development of composites containing various volume loads of BST, NZF, or combined loadings to tune dielectric and magnetic properties. It was found that by increasing the volume fraction of BST, one can effectively increase the permittivity of a bulk sample. Similarly, by increasing the volume loading of NZF, a samples permeability can also be increased. These results are promising for the development of tunable NLTLs.
