Quasihybrid scheme of nonuniform rational B‐spline–uniform geometrical theory of diffraction method for radiation of antennas

“…In the area of electromagnetic simulation, the NURBS technique was first introduced into physical optics (PO) to calculate radar cross section of electrically large targets [1,2] and since then, the NURBS-PO method was carefully studied in various applications [3][4][5]. In the method of moment (MoM), lots of studies have been made from basic thoughts to different basis functions to try to absorb the NURBS technique in Refs.…”

“…There have increasingly been requests for low phase-noise in oscillator design, because it determines the overall performance of the systems [2]. The double-split ring resonator (D-SRR) [3] with munegative (MNG) metamaterials has been reported in the design of resonators with band-rejected performance [3]. D-SRRs are appropriate for the oscillators and other circuits required for a high-loaded quality factor, (QL) and band-stop resonant performance due to their sharp band-rejection characteristic [3].…”

“…MNG metamaterial is artificially engineered material exhibiting features not readily available in natural materials. The split ring resonator (SRR), which has as its theoretical basis Veselago's work on metamaterial in the late 1960s [3], has engendered great research recent interest. After Pendry's pioneering experimental work on the SRR of negative permittivity and permeability in 1992 [4], a great deal of research has been reported in the literature.…”

Novel NURBS‐PO method for efficiently analyzing antenna around an electrically large platform

“…In 1992, Perez and Catedra [1] first introduced the nonuniform rational B spline (NURBS) surface modeling technology into the field of high frequency electromagnetic computation. Since then, electromagnetic computational methods [2–7] based on NURBS modeling have drawn considerable attention due to the advantages of high modeling precision and little number of surfaces. In 2001, physics optics (PO) was successfully used to calculate the disturbed pattern of antenna around a platform modeled with NURBS surfaces [3].…”
