“…Radiation from slots and seams is of greater concern as the speed of the electronic designs increases [9][10][11][12][13][14][15][16][17]. Thin-slot formalism permits inclusion of conducting plates with arbitrarily narrow apertures or gaps without requiring any corresponding need to reduce the cell size to the gap width or depth for the FDTD analysis.…”

Abstract-This paper brings forward a simple local approximation finite-difference time-domain (FDTD) method for the analysis of short apertures with a finite thickness. By applying the equivalence principle together with a simple local approximation, the varying field distribution is accurately derived. The updating equations for the slot field can be derived by casting the field distributions into the contour paths containing the apertures. The method has been applied to two problems and the results are compared with the high-resolution standard FDTD simulation results and the measurement results. The accuracy of the proposed method is verified from the comparison of both the field distribution and the time-domain and frequency-domain slot coupling results. It is demonstrated that the local approximation is highly efficient and timesaving, and the present method is stable, numerically and computationally efficient.

“…Recently, EBGs and PBGs are of great interest due to their extraordinary properties and potential applications e.g., filters, polarizers, substrates for radiating elements, or optical switches [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. FSSs find also application in polarizers and polarization rotators to change the polarization state of an electromagnetic wave [16,17].…”

Abstract-In the paper, the analysis of electromagnetic wave scattering from multilayered frequency selective surfaces is presented. The surface is composed of periodically arranged posts with irregular shapes. The multimodal scattering matrix of such structure is derived and the transmission and reflection characteristic for the structure with arbitrary plane wave illumination are calculated. The exact fullwave theory based on the hybrid approach employing mode-matching method and finite-difference frequency-domain (FDFD) technique is applied to develop an efficient theory to analyze such structures. The validity and accuracy of the approach are verified by comparing the results with those obtained from alternative methods and own measurements of manufactured periodic structures.

“…Its advantages include dramatic reduction of aerodynamic drag and the weight of arrays, wide angle coverage of 360 • , space-saving, reduction of radar cross-section, as well as potential increase in available aperture. Much of the existing research in conformal antenna array has mainly focused on the design of antenna elements [3][4][5], the pattern synthesis and optimization of conformal antenna [6][7][8][9][10]. The high resolution direction of arrival (DOA) estimation algorithms [11][12][13][14] based on conformal antenna array has not been studied as intensively [15,16].…”

Abstract-The pattern of each element in conformal array has a different direction for the curvature of conformal carrier, which results in polarization diversity of conformal array antenna. Polarization parameters of incident signals are considered in snapshot data model in order to describe the polarization diversity of conformal array antenna. It is required that the polarization parameters and direction of arrival (DOA) of incident signals are estimated together. An integrated frequency and DOA estimation method is proposed in this paper for cylindrical conformal array antenna. The frequency estimation of signal source is obtained by constructing state-space matrix. Through well-designed configuration of elements on cylindrical carriers along with estimation of signal parameters via propagator method (PM), the decoupling scheme for DOA and polarization parameters is implemented. A novel parameter pairing method for frequency and DOA of multiple sources utilizing the interpolation technique is given, based on which the fast frequency-DOA estimation algorithm is developed. Effectiveness of the proposed method is demonstrated by simulation experimental results.
