Microwave imagers featuring a fully electronic scanning are highly demanded in security, industrial, and medical applications. Planar multistatic arrays operating at close ranges offer exceptional image resolution and illumination coverage compared to conventional far-field imaging. Novel solutions for synthesizing multistatic arrays for close range imaging with a scalable topology are introduced in this work along with detailed experimental verifications in the millimeter-wave range. Consequently, an electronic microwave imager based on modern digital-beamforming techniques has been successfully realized. High quality imaging of humans has been demonstrated, which represents a key milestone for the future generations of personnel screening systems required for securing air traffic as well as critical infrastructures. The work establishes the theoretical foundations for designing electronic microwave imagers, while addressing the associated challenges, e.g., image reconstruction, illumination adjustment, signal processing, hardware architecture, calibration technique, and results interpretation. The achieved three-dimensional complex-valued images open vast opportunities for new applications to effectively utilize the advanced capabilities of microwave imaging.

Clean, sustainable energy solutions from the geniuses of our past and the visionaries of our future • Explores five great but nearly forgotten minds of the past--John Worrell Keely, Nikola Tesla, Viktor Schauberger, Royal Raymond Rife, and T. Townsend Brown--and their revolutionary discoveries • Reveals information from leading experts on cold fusion, zero-point energy, power from water, antigravity, and the free-energy potential of the Searl Effect Generator As the global need for clean, renewable energy grows and the shortage of viable large-scale solutions continues, it is time to look to the geniuses of our past and the visionaries of our future for answers. Taking inspiration from Albert Einstein’s statement that “Problems cannot be solved by the same level of thinking that created them,” Finley Eversole explains that the key to a pollution- and poverty-free future of infinite energy lies not in pursuing one single method, but in investigating all the possibilities--in uniting as a world in creative pursuit of global transformation. Exploring five nearly unknown geniuses of our past--John Worrell Keely, Nikola Tesla, Viktor Schauberger, Royal Raymond Rife, and T. Townsend Brown--and their revolutionary discoveries about free energy, electricity, water vortex motion, electric ray and super-microscope technology, and antigravity, this book helps to restore their long-suppressed scientific legacies and bring us one step closer to the destiny they foresaw. Eversole has gathered research from leading experts on cold fusion, zero-point energy, power from water, and the free-energy potential of the Searl Effect Generator to reveal technologies that work with Nature’s laws and that, if fully implemented, could establish sustainable energy systems in a single generation.
