Duggan's latest patents include the "Latitude Optimized Satellite Constellation" and the "Tunable Metasurface Device." The Latitude Optimized Satellite Constellation patent describes a system that includes a plurality of satellites synchronized in a Waves constellation. This system is designed to maximize coverage of a target ground location at predetermined latitudes with a minimal number of satellites. The satellites orbit the Earth in multiple orbital planes, evenly spaced in right ascension of ascending node, and are synchronized to cross the Equator together.
The Tunable Metasurface Device patent details a metasurface device that consists of two sub-cells, each configured to exhibit distinct resonant electromagnetic field (EMF) responses. These sub-cells include a patterned layer and a variable impedance element that can change the EMF response based on a control signal. The integrated EMF response of the metasurface unit cell is achieved through the cascaded configuration of the two sub-cells.
