Abstract Magnetotelluric (MT) data are often distorted by near-surface small-scale lateral heterogeneities. Inverting MT may produce artifacts or false anomalies, leading to unreliable interpretation. This problem can be avoided inverting the phase tensor (PT), which is known free of galvanic distortion. However, PT inversion strongly depend on initial prior model, because itself does not conta...

In recent papers Caldwell, Bibby and Brown (2002, 2003) (hereafter referred to as CBB) have introduced a new and elegant method for analysing magnetotelluric (MT) data which can be applied directly to galvanically distorted data in a regional conductivity structure of any dimension. It is therefore more general and direct than previous methods (e.g. Bahr, 1988; Groom and Bailey, 1989; Smith, 19...

The most revealing description of electromagnetic (EM) distortions due to near-surface inhomogeneities and topography is in terms of galvanic and inductive effects. In either case, the distorted electric ankt magnetic fields can be best visualized as a vectorial sum of primary and secondary fields. Secondary electric fields due to electric charge build-up in the galvanic case persist to the lon...

 provision of large, stress-bearing area  excellent fatigue strength  good shock absorption  reduced galvanic corrosion  no need to have access to far-side of adherend to make joint  bonding is possible on dissimilar materials  provision of smooth contours and sections around joint areas  sealing  improved damping which increases structural stiffness  reduction in distortion and metal...

Distributed power-supply systems are an attractive solution to meeting the requirements (redundancy, modularity, battery backup, etc.) for the next generation of power-supply systems. In addition, the normalization regarding power factor and total harmonic distortion (THD) makes it necessary to include the power-factor correction in the input stage in those architectures. This paper presents a ...
