This article proposes a planar magnetoelectric resonator (PMER) as the element of broadband dual-polarized (DP) and circularly polarized (CP) reflectarray antennas (RAs). The PMER is realized by introducing split in dual rhombic rings, which flats vertical structure for magnetic resonance common (ME) element. Due to isolated electric resonant modes PMER, anisotropic characteristic achieved independently manipulate reflection phase among two orthogonal polarizations reflect CP incident wave...
A field-based circuit model (FBCM) is proposed to reveal impedance, near-field, and far-field performance of acoustically actuated piezoelectric (PE) antenna by introduction electromagnetic induction into PE equations impedance analysis at the boundary. To make more practical, induced current on body analyzed near-field compression large permittivity material formulated. Closed-form expressions are built conveniently evaluate parameters. Furthermore, FBCM method validated precise vehicles,...
A metal-loading (ML) method is proposed in this article to increase effective length, near-field magnitude, and radiation efficiency for an acoustically actuated piezoelectric antenna (PEA). field-based circuit model (FBCM) utilized characterize the metal-loaded PEA (MLPEA) by introducing fields into equations impedance analysis at boundary. Furthermore, current distribution within PE cylinder on loaded metal rod calculated finite element modeling (FEM) formulated with piecewise functions....
An AI-enhanced modal decomposition method is proposed in this paper for fast and efficient high-speed multilayered PCB modeling integrity. Depending on patterns of local structures, divides a given interconnections into independent cells, take advantages different evaluation methods (analytical, numerical, AI-based) to analyze each cell. With the assistance AI technology, compound find way compute complex structures effectively method. We briefly introduced architecture workflow method, then...
