In-situ high-temperature electromagnetic characterization of ceramic composite tiles for strategic applications

In this paper free space microwave measurement setup has been integrated with the high temperature (HT) cell for the in-situ electromagnetic characterization. The experimental-setup is capable of operating in the frequency range from 5.85–40 GHz along with the in-situ material characterization from ambient to 1200°C. In this present work, experiment has been carried out for X band (8.2–12.4GHz) frequency region. The measurement system has been integrated with the dedicated software, which interfaces with the vector network analyzer and the temperature controller. In order to validate the experimental set-up, measurement is performed for the standard samples, after that the material under test is evaluated for characterization. Here the proposed integrated set-up has been used for testing of ceramic samples which are quite often used for application in defence strategic products. The proposed integrated set-up is ideally suited for electromagnetic characterization of day to day routine samples as well as as for various industrial applications.
