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.

这项小型企业技术转移研究（STTR）I期计划将扩展用于电气可调的微波设备应用的薄膜薄膜材料的类型，包括谐振器，过滤器和相位变速器。例如，相位变速器在分阶段阵列天线中起着至关重要的作用。与依赖磁场来改变材料的磁渗透性的常规基于铁氧体的设备相反，铁电设备具有电介电常数或相应的介电常数，通过施加的电场变化。电气而非磁性可调性可以更紧凑，更有效的设备。薄膜铁电剂比散装铁电的进一步优势，因为它们在较低的电压下运行。 在此I阶段ISTTR项目中，F＆S/Luna创新及其大学研究合作伙伴将开发一种新的材料，用于基于有机聚合物而不是陶瓷铁电材料的电气可调的微波设备应用。聚合物的优点包括低成本，易于加工性，低介电常数和损失切线，以及可以通过有机合成为给定设备优化的广泛潜在材料的多功能性。这项技术将彻底改变微波开关的制造和与现有组件技术相比，通过降低尺寸，成本和功率要求，同时提高性能，通过降低尺寸，成本和功率要求来转移组件。
