Numerical Reconstruction and Applications of Acoustic and Electromagnetic Ultra-Wideband Localized Pulses Generated by Dynamic Aperture Antennas
… energy LWs that can be generated by dynamic aperture antennas with independently addressable elements. The reconstruction techniques are based on Huygens and Rayleigh-Sommerfeld integral I and II representations, both in the time and frequency domains. In contradistinction to the Weyl …

Optimal Reconfiguration of Thermally Distorted Wire Mesh Reflectors for Large Space Antennas
… reflector surface precision for large aperture antennas deployed in space has not been completely resolved. This feasibility study advances an approach that represents a fundamental divergence from conventional techniques. Specifically, an underconstrained structural system in the form …

Analysis of infinite arrays of arbitrarily shaped planar radiating elements using a Floquet mode based Method of Moments approach
Large phased array antennas are theoretically capable of delivering the directive gain of similarly sized aperture antennas while offering electronic beam scanning capabilities and greater operational flexibility. Unfortunately, the high cost associated with large phased antenna arrays has limited …

Array Signal Processing for Communications from High Altitude Platforms and Other Applications
… than when using the same number of aperture antennas. Its advantages in payload reduction are even more significant. The adaptive beamforming techniques are also applied in the receiver design for high data rate OFDM signal transmission in the fast-varying underwater acoustic …

Rectangular waveguide narrow-wall longitudinal-aperture antenna arrays for high-power applications
… rectangular waveguide narrow-wall longitudinal-aperture antenna arrays for high power applications. The best narrow-wall longitudinal-aperture array designs in the work are called the double-narrow-wall-slot-HPB-array and the double-split-waveguide-HPB-array. The …
