This Small Business Technology Transfer Research (STTR) Phase I program will expand the types of thin filmferroelectric materials for electrically tunable microwave device applications including resonators, filters, and phase shifters. Phase shifters play an essential role in phased array antennas, for example. As opposed to the conventional ferrite-based devices, which rely on magnetic fields to vary the magnetic permeability of the material, ferroelectric devices possess an electric permittivity or, correspondingly the dielectric constant, that is varied by an applied electric field. Electrical rather than magnetic tunability allows more compact and power-efficient devices. Thin film ferroelectrics have further advantages over bulk ferroelectrics in that they operate at lower voltages. In this Phase I STTR project, F&S/Luna innovations and their university research partners will develop a new class of materials for electrically tunable microwave device applications that are based on organic polymers rather than ceramic ferroelectric materials. The advantages of polymers include low cost, easy processability, low dielectric constant and loss tangent, and the versatility of a wide range of potential materials that can be optimized for a given device through organic synthesis.This technology would revolutionize the fabrication of microwave switching and phase shifting components by reducing size, cost and power requirements while improving performance compared to existing component technologies.

这个小企业技术转移研究（STTR）第一阶段计划将扩大电调谐微波器件应用，包括谐振器，滤波器和移相器的薄膜铁电材料的类型。例如，移相器在相控阵天线中起着至关重要的作用。与依赖于磁场来改变材料的磁导率的常规铁氧体基器件相反，铁电器件具有通过施加的电场而改变的电容率或相应地介电常数。电而不是磁可调谐性允许更紧凑和功率效率更高的设备。薄膜铁电体相对于体铁电体具有更多的优点，因为它们在较低的电压下工作。 在第一阶段的STTR项目中，F S/Luna创新公司及其大学研究合作伙伴将开发一类新的材料，用于基于有机聚合物而不是陶瓷铁电材料的电可调谐微波器件应用。聚合物的优点包括低成本、易加工、低介电常数和低损耗角正切、以及通过有机合成可以针对给定器件优化的多种潜在材料的多功能性。与现有的元件技术相比，该技术将通过减小尺寸、成本和功率要求而彻底改变微波开关和相移元件的制造，同时提高性能。
