Novel Materials And Devices For Terahertz Detection And Emission For Sensing, Imaging And Communication, Naznin Akter

FIU Electronic Theses and Dissertations

Technical advancement is required to attain a high data transmission rate, which entails expanding beyond the currently available bandwidth and establishing a new standard for the highest data rates, which mandates a higher frequency range and larger bandwidth. The THz spectrum (0.1-10 THz) has been considered as an emerging next frontier for the future 5G and beyond technology. THz frequencies also offer unique characteristics, such as penetrating most dielectric materials like fabric, plastic, and leather, making them appealing for imaging and sensing applications. Therefore, employing a high-power room temperature, tunable THz emitters, and a high responsivity THz detector is essential. …

Additive Manufacturing And Applications Of Silica Glass Materials, Omena Okpowe

FIU Electronic Theses and Dissertations

The difficulty in shaping and fabrication of miniaturized features on glass structures using conventional fabrication techniques makes the recent advancements in glass manufacturing necessary. Pioneer efforts towards glass additive manufacturing have proven to be the nexus between the past and the future of glass fabrication.

Additive manufacturing potentially allows for speed, scalability, environmental and cost friendliness, high resolution as well as flexibility for functional glass materials. Adapting additive manufacturing methods toward glass fabrication is thus of great importance. We first fabricated three dimensional doped and undoped Borosilicate glasses via stereolithography which exhibited comparable optical properties to commercial glasses, irrespective of …
