Nowadays, Wi-Fi routers are present in all aspects of our lives, at home and in the workplace. In all such cases, however, a limited number of users can result in a waste of wireless energy. Our project aimed to reclaim this unused energy with a meta-surface, a manmade structure with specific characteristics for specific wavelengths. With a meta-surface we can collect the wasted energy and reuse it. For instance, an IoT network can be powered from a such a surface. The design of our meta- surface was developed using a HFSS and was validated using simulations.

The need to protect privacy, particularly that of personal and national-security information, becomes increasingly important as technology advances. Individuals' capability to use cameras to capture images of sensitive areas has led to the strategy of dazzling (blinding) cameras with lasers. Continuous wave (CW) lasers can potentially harm both cameras and human vision due to their high-power density. This project aimed to provide a "proof of concept" demonstrating that pulsed lasers can outperform CW lasers in several parameters, including power density and unwanted damage. We used MATLAB to analyze the number of consecutive dazzled frames in video footage to identify optimal results for dazzling applications.
Keywords: dazzling applications, lasers and applications
