The results here reported—all corroborated with full-wave simulations—may revolutionize the concept of wireless links based on Bessel beams at millimeter waves.

Abstract: This letter presents a low-complexity parasitic pixel strip (PPS) structure for array antenna to generate six radiations with flexible beam control. To realize multibeam operation, three ...

Key methods include Kirchhoff Migration, a ray-theory-based approach; wave-equation-based techniques such as Reverse Time Migration (RTM); and Gaussian Beam Migration (GBM), which combines the ...
