A well-conditioned coupled set of surface (S) and volume (V) electric field integral equations (S-EFIE and V-EFIE) for analyzing wave interactions with densely discretized composite structures is presented. Whereas the V-EFIE operator is well-posed even when applied to densely discretized volumes, a classically formulated S-EFIE operator is ill-posed when applied to densely discretized surfaces. This renders the discretized coupled S-EFIE and V-EFIE system illconditioned, and its iterative solution inefficient or even impossible. The proposed scheme regularizes the coupled set of S-EFIE and V-EFIE using a Calderόn multiplicative preconditioner (CMP)-based technique. The resulting scheme enables the efficient analysis of electromagnetic interactions with composite structures containing fine/subwavelength geometric features.Numerical examples demonstrate the efficiency of the proposed scheme.

“…The low-cost antenna for millimeter-wave applications, using the rod configuration made from dielectric material was proposed by Huang and Wang [2006]. The detailed analysis of the rod antenna was reported by Whitman et al [2006] and Ando et al [2005Ando et al [ , 2003. Some previous work utilized the horn waveguide as the excitation for the rod.…”

Switched‐beam array of dielectric rod antenna with RF‐MEMS switch for millimeter‐wave applications

A conformal dielectric rod antenna array with operating frequency of 11.2 GHz is investigated, designed, and measured. This antenna array is combined with a single pole double throw radio frequency microelectromechanical systems (RF‐MEMS) switch to realize switched‐beam performance. Moreover, this antenna array exhibits uniform radiation performance for different scan angles with no grating lobes. The characterization and measurement of the antenna system have been performed. The measured radiation pattern of the antenna in the anechoic chamber is in good agreement with the simulated antenna pattern. The measured antenna with the RF‐MEMS switch has 13.5 dBi realized gain, −15 dB sidelobe level, 22° half‐power beamwidth, and 7.3% (fractional) bandwidth (or 800 MHz) at 11.2 GHz.

“…One of them is the Yee-mesh-based imaginary-distance beampropagation (BPM) method developed by Lee [4], [5]. This method has the advantage that the obtained eigenmode profiles can be utilized as an incident field of the finite-difference time-domain (FDTD) method, since all the electromagnetic field components located on Yee's mesh are simultaneously analyzed [6].…”

Abstract-A novel Yee-mesh-based finite-difference fullvectorial beam-propagation method is proposed with the aid of an implicit scheme. The efficient algorithm is developed by splitting the propagation axis into two steps. The eigenmode analysis of a rib waveguide is performed using the imaginary-distance procedure. The results show that the present method offers reduction in computational time and memory, while maintaining the same accuracy as the conventional explicit Yee-mesh-based imaginary-distance beam-propagation method. It is demonstrated by the analysis of a polarization converter that the present method can be used for not only the eigenmode analysis but also the propagating beam analysis.
