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.
