We have stacked subwavelength gratings (SWGs) on a single substrate to create a compact, integrated circular polarization filter. The SWGs consist of a wire grid polarizer and a broadband form-birefringent quarter-wave plate (QWP). Rigorous coupled-wave analysis was used to design the QWP for operation over the 3.5-5.0-mum wavelength range. The fabricated silicon broadband QWP exhibited a phase...

This paper reports on a robotic assistant for ambient intelli gent meeting rooms and also for human-centred environments in general. The usefulness of such an “embodied” assistant as a video conferencing tool for sites not possessing an intelli gent meeting room and as a mobile extension of an "intelli room" is discussed, along with possible scenarios. The most important benefit is probably the...
