SBIR Phase I Final Technical Report

Abstract

The main purpose of this program, a Phase I SBIR effort, was to demonstrate the feasibility of constructing a fast void detector that can detect and localize voids with a quantifiable detection limit superior to a capacitive void sensor. The project used modeling and simulation of the radio- frequency (RF) sensor and environment, designed RF elements for the harsh environment, and fabricated the devices for temperature and pressure requirements. The project concluded with a demonstration of the system and feasibility of approach. First, the project performed theoretical work to simulate the system capabilities. Second, the project refined the RF sensor designs. Third, the effort fabricated devices. Fourth, the project demonstrated feasibility with a demonstration of the technology, individual components, and integrated elements. We assess that the project ended at Technology Readiness Level 3 (TRL-3) and demonstrated the feasibility of our concept.
