This paper presents a modeling technique for output-signal prediction of a waveguide probe when scanning a tilted long crack. The modeling technique establishes a cavity by placing a hypothetical conductive plane within the waveguide at some distance away from the probe–crack mouth. The position of the plane is iteratively changed until the appropriate… (More)

A subdomain method of moment formulation is proposed to model the problem of an open-ended coaxial probe radiating into a metal with a surface-breaking crack of arbitrary depth profile. The proposed formulation is capable of treating effectively the unknown magnetic current over the arbitrary-shape common aperture. By using the dyadic Green’s function, it… (More)

This paper proposes an efficient modeling technique for time-domain electromagnetic analysis of a multilayered structure, using the surface equivalent principle and mixed-potential integral equations (MPIEs). First, the surface equivalent principle is used to replace the nonmetallic parts in each layer interface of the structure by prefect electrically… (More)

A great number of existing power transmission lines have aged throughout the world. A considerable proportion of them are located in the environments that exacerbate their corrosion and erosion process. In-time detection of defects necessitates the use of nondestructive testing (NDT) techniques. Scanning the lines with robots and helicopters are the methods… (More)

In addition to the advantages of distributed generation (DG) sources, also it would have disadvantages such as harmonic distortions generation and changing in short-circuit current. Harmonic distortion generation may exceed from permissible harmonic level and cause problem. Furthermore, the change in short-circuit current can cause performance of incorrect… (More)

The paper adopts a comprehensive modeling technique to investigate the effect of frequency-dependent characteristics of grounding system in a grid-connected photovoltaic (PV) system on the overvoltages caused by lightning strikes on the nearby overhead line. In this technique, the frequency response of grounding system is determined using an electromagnetic… (More)

A hybrid method is presented for modeling realistic ground penetrating radar systems to detect multiple underground conducting or dielectric targets. The model combines the method of momentpsilas solution of the frequency domain thin-wire electric field integral equation to treat the dipole antennas and the finite difference time domain technique to handle… (More)
