The main goal of this research is to address several main challenges in the realization of practical phononic crystal (PnC)-based devices for wireless signal processing at RF frequencies by 1) relaxing the extreme geometry and fabrication constrains, 2) developing practical PnC devices based on surface acoustic-waves that eliminate the need for thin film and undercutting, and with the broad impact of 3) developing efficient low-impedance electro-statically tunable PnC crystals devices that can potentially eliminate the need for piezoelectric materials. To achieve these goals we will develop a new PnC material platform based on an array of pillar structure on a thin slab material or on an infinite substrate (for surface waves) that also constitute the intellectual merits of this effort. The proposed material platform will be used to demonstrate chip-scale spectral analysis at the L band (i.e., 1 -2 GHz) frequencies.

本研究的主要目标是通过以下方式解决实现用于RF频率下的无线信号处理的基于实用声子晶体（PnC）的设备中的几个主要挑战：1）放松极端几何形状和制造约束，2）开发基于消除薄膜和底切的需要的表面声波的实用PnC设备，并且具有3）开发有效的低阻抗静电可调谐PnC晶体器件的广泛影响，其可以潜在地消除对压电材料的需要。为了实现这些目标，我们将开发一种新的PnC材料平台，该平台基于薄板材料或无限衬底（用于表面波）上的柱结构阵列，这也构成了这项工作的智力优势。拟议的材料平台将用于演示L波段的芯片级光谱分析（即，1 - 2GHz）频率。
