An infrared phased array antenna design using leaky-wave elements is presented. The leaky-wave mechanism is utilized to produce scanning in the ϕ=90° plane while phase tuning by varying distance between the leaky-wave elements produces scanning in the ϕ=0° plane. The combination of these two allows for 2D beam scanning. The applications of such 2D phased arrays lies in highly directive, broadband...

Ethical training in the classroom offers engineering students the opportunity to assess theoretical frameworks and consider crucial diverse perspectives that they can apply in the workplace. With practice, and exposure to decision-making processes supported by ethical theory, students can develop the agility to consider dilemmas from multiple ethical perspectives in order to make more astute decisions...

The design of plane Fresnel zone plates, and binary-staircase kinoforms, has been analyzed in this paper for a non-imaging application aimed to increase the performance of point-like detectors. They maximize the irradiance at the focal point of the diffractive element maintaining some constrains in the lateral size of the element. The design of the binary-staircase kinoform has been described as an...
