This proposal is a Platform Grant renewal. Our previous grant allowed us to develop the key characterisation facilities and enabled us to understand fully the materials that were the study of the grant. These materials were low loss microwave dielectrics, ferroelectric materials and thin films of these materials.The Platform renewal will build upon some remarkable discoveries that the team, including the key PDRAs, has made over the last 4 years and centre around functional materials for devices operating from microwave to millimetre wave or from MHz to THz. First it is important to explain the Materials Science progress that forms the underpinning technologies that will enable us to use the Platform grant to build new devices. At the heart of microwave devices are resonators that require low dielectric loss or very high Q factor and the target is to aim for very high Q dielectrics. Our previous Platform grant and indeed prior support from EPSRC allowed us to discover very low loss, high Q materials. This culminated in two significant discoveries.1 First we were able to use low loss resonators as sensors for liquid sensing2 Second, we demonstrated that by using a very high Q resonator we could achieve maser action at room temperatureand in Earth's field - published in Nature 2012.This platform grant will enable us to build upon these discoveries.1) Advanced Characterisation: In the first theme the aim will be to carry out a series of qualifying experiments to determine the best possible conditions and materials for sensing over the wide range of frequencies available to us (Hz to THz)2) Microwave and mm wave sensors: The third theme takes the science to application. We will use the resonators for analysis of ions, biomolecules, proteins and cells. The sensitivity of the resonators allows nanolitre quantities to be analyzed very rapidly for possible cancer cell detection in blood and bacteria in water.3) "UMPF" and "HEP" Cavities: In the second theme we aim to make UMPF (Ultrahigh Magnetic Purcell Factor) and "HEP" (High Electric Purcell) cavities. These are small resonant cavities with a very high Q given the very small mode volume and success here will enable us to improve electron paramagnetic sensing dramatically and enable single cell detection. Success in these new themes for the Platform would represent a remarkable step-change in technology.

该提案是平台赠款续订。我们以前的赠款使我们能够开发关键的特征设施，并使我们能够充分了解赠款研究的材料。这些材料是低损耗的微波介电，铁电材料和这些材料的薄膜。平台更新将建立在一些引人注目的发现的基础上，包括关键PDRA在内的团队在过去的4年中已经制造了，并围绕着从微波炉到MILIMETER WOVE或从MHz到THZ的设备的功能材料。首先，要解释构成基础技术的材料科学进步非常重要，这些技术将使我们能够使用平台赠款来构建新的设备。微波设备的核心是需要低介电损耗或Q因子很高的谐振器，目标是旨在实现非常高的Q介电性。我们以前的平台赠款以及EPSRC的事先支持使我们能够发现非常低的损失，高Q材料。这是两个重大发现的最终原因。1首先，我们能够使用低损耗的谐振器作为液体传感2秒的传感器，我们证明，通过使用非常高的Q谐振器，我们可以在地球领域的室温下实现Maser Action-在《地球自然界》中发表 - 2012年在2012年发表。平台Grant将使我们能够构建这些典型的典型特征。为了感知我们可用的广泛频率（Hz至THZ）2）微波和MM波传感器：第三个主题将科学带到了应用。我们将使用谐振器分析离子，生物分子，蛋白质和细胞。谐振器的敏感性允许对纳米列数的量进行非常迅速的分析，以使水中的血液和细菌中可能的癌细胞检测。3）“ UMPF”和“ HEP”腔：在第二个主题中，我们旨在使UMPF（Ultrahigh Maginage Purcell因子）和“ HEP”（高电动Purcell）（High Electric Purcell）（High Electric Purcell）。鉴于非常小的模式体积，这些是很小的响应腔，Q非常高，在这里的成功将使我们能够显着改善电子顺磁性传感并启用单细胞检测。这些新主题的成功将代表技术的显着阶梯变化。
