“…The description of the WCIP method is more detailed in literature,() and so we describe here just the main steps of the iterative procedure. The wave concept is introduced by writing the voltage and the current in terms of outgoing and incoming waves denoted, respectively, by ( A i ) and ( B i ) tangential to each edge of the network.…”

“…Over the last two decades, the WCIP method has already shown its powers to resolve the radiation and scattering in electromagnetic problems. () This method was proved to be particularly interesting and efficient for analysis of a wide range application of planar circuits. () Recently, the method has been developed to study almost periodic networks with rectangular topology excited by localized sources, and it has been successfully applied for modeling the metamaterial lenses and quasi‐periodic lumped circuits.…”

Summary This paper deals with an RLC circuit network with triangular or hexagonal grid. It is about a planar equilateral triangular grid where the passive (resistor, capacitor, and inductor) or active (voltage source for example) components are located at the sides or/and at nodes attached to the ground. The planar graph is oriented by three main direction vectors phase shifted to 60° degrees. The wave concept iterative process (WCIP) method was employed to the theoretical formulation of the problem. In the formulation, the potential difference across each circuit component is represented by an auxiliary source defined in the spectral domain. The proposed theory is developed into two definition domains: a spectral domain in which periodicity and coupling between the circuit components are defined and a spatial domain describing the network topology and imposing the continuities conditions (Kirchhoff laws). The transition between the spectral and spatial domain is ensured by the so‐called fast hexagonal Fourier transform. Numerical applications demonstrate the ability of the method for solving the inhomogeneous triangular lattices. Various conceptions have been proposed including an RL, RC, and RLC triangular network circuit, a perturbed triangular RLC circuit, and a triangular circuit excited by many lumped sources.

The aim of this manuscript is to present the application of an iterative method based on the concept of transverse wave to analyze the packaging (passive element and substrate) miniaturization effect on the characteristics of an active planar circuit structure. This approach consists in the substitution of the active element by one auxiliary source, and connection is assumed by microstrip line as passive element deposited on one unique substrate. An implementation of the presented theory is shown by extraction of S-parameters and impedances of the active circuit using MATLAB program codes.

Abstract-The Wave Iterative Process is applied and validated for the study of the scattering of a plane wave by a multiple metallic dipole diffraction structure. The case of a single metallic dipole is treated, at first in normal incidence, than arbitrarily placed with respect to the incident wave. A double dipole scattering structure is studied, mutual influence being taken into account. The diffraction system is further enlarged to 5 randomly placed dipoles, the results issued from the WIP study being compared with those given by the Moments Method. Finally, the possibility of taking into account a very large number of dipoles is examined, by introducing an equivalent dipole distribution. The influence of this approximation on the WIP precision is presented.
