“…These methods include the partial element equivalent circuit (PEEC) method [1], the transmission line matrix (TLM) method [2], the finite-difference time-domain (FDTD) method [3,4], and the finite difference frequency-domain (FDFD) method [5]. The PEEC method, FDFD method, and FDTD method are full wave methods, and more wide applied to solve the electromagnetic problems [6][7][8][9][10][11][12][13], which can analyze the model precisely. Also the Quasi-TEM approach was proposed to analyze the multilayer PCB [14,15].…”

The power/ground bounce seriously affects circuit performance. Several methods have been used to simulate it. These methods ranged from simple lumped circuit models to full-wave (dynamic) three-dimensional Maxwell equations simulators. In this paper, the method of time-domain full-wave analysis is used to simulate the noise caused by three types of different excited sources in the power distribution networks (PDNs), to research the effect of source types on the noise and to analyze the effect of source property, dielectric materials, and boundary conditions on noise voltage and mutual impedance between ports.

Abstract-In this paper a novel intelligent method to identify an unknown medium (type of apodization and chirping) is developed. Our consideration is concentrated on complex fiber Bragg Gratings. For realization of the idea the Genetic Algorithms (GAs) is used. So, GAs is used to solve inverse scattering problem for reconstruction of nonuniform or complex fiber Brag gratings. In this method, the reflection coefficient measured in practice is inserted to a suitable algorithm.According to the proposed method, first medium discrimination is performed between predefined large classes of mediums and then the whole and necessary parameters for reconstruction of the medium are extracted. Full numerical method is used for compare of the results obtained from the presented algorithm. Our simulation shows good agreement between them. So, a novel method for identification and discrimination of optical mediums especially complex Bragg Gratings is presented. Finally the presented method can be used to identify optical mediums and complex Bragg Gratings systems.

“…This is among the main advantages of AWSA arrays, which is open to more theoretical investigations in the future. As the main standard requirement for such an improvement, Green's function formulation of the annular waveguide and MoM analysis of the slotted annular waveguide (AWSA) are the vital steps to be performed as in other similar design approaches [14][15][16][17][18][19][20][21][22][23].…”

Abstract-Detailed procedure for Green's function derivation of an annular waveguide is presented in this paper for the first time. The proper components of the electromagnetic fields along with their corresponding Green's functions will be derived in a useful and applicable form. Based on the derived Green's functions, a proper set of integral equations are derived in a novel general form which MoM solution will lead to complete slot field distribution in the annular waveguide slot antenna (AWSA). The proposed theory is found having high value in circuit modelling and array design of such novel antenna structures in the future.
