The authors introduce new architectures that permit the operation of antenna arrays over several octaves. The concept is based on adding elements in between and of half the size of other elements in order to extend one octave in frequency. This wideband array with variable element size (WAVES) antennas was demonstrated by calculations and by measurements(More)
The inherent intermittency of the two fastest growing renewable energy sources, wind and solar, presents a significant barrier to widespread penetration and replacement of fossil-fuel sourced baseload generation. These intermittencies range from short term ramp events experienced by wind farms to the diurnal fluctuation of solar installations. In this(More)
The Yamburg gas condensate field in northwestern Siberia sits atop the largest natural gas and petroleum basin in the world. Infrastructure related to the extraction and transport of natural gas is both geographically widespread, and has been shown to affect a much larger area than the immediate infrastructural footprint. Because field studies of the(More)
