The main purpose of this paper is to design, implement and measure a new sample of mantle cloak. A new method called mantle cloak is introduced by cloaking an object by a single, conformal meta-surface which can drastically suppress the scattering of the desired object. In this paper, a grid lattice is placed around a dielectric object as the cloaking structure. Previously, this FSS has been ut...

Abstract The Sinai Peninsula is a subplate located between the African and Arabian plates. It an important in world; however, this region poorly understood because of shortage geophysical data. Thus, study focuses on built three-dimensional (3D) high-resolution forward model crustal thickness with new tectonic structural evaluation to understand area tectonically determine its lithospheric thic...

Geomagnetic jerks are sudden changes in the geomagnetic field secular variation related to outer core flow patterns. Finding geophysical phenomena provides a vital contribution better understand behavior. Here, we link occurrence with one of most relevant features nowadays, South Atlantic Anomaly (SAA), which is due presence reversed flux patches (RFPs) at Core-Mantle Boundary (CMB). Our result...

The Azores archipelago is a classic expression of a hotspot that has interacted with a mid-ocean ridge. A variety of geochemical studies and geophysical observations point to the influence of some sort of mantle plume on the formation of the Azores Plateau and the adjacent Mid-Atlantic Ridge (MAR), but the mantle structure beneath the Azores has not heretofore been imaged tomographically at a s...

Introduction. The internal structure of a planet provides essential clues about its origin and evolution. At present we can only claim insight into the internal structure of the Earth and Moon. Seismology has provided by far the most specific information on the interior of these two bodies. However, because no seismic data are available for Mars, it is neccessary to look elsewhere for constrain...

The evolution of strain and development of material anisotropy in models of Earth’s mantle flow convey important information about how to interpret the geometric relationship between observation of seismic anisotropy and the actual mantle flow field. By combining feature extraction techniques such as path line integration and tensor accumulation, we compute time-varying strain vector fields tha...

Materials circulation in Earth’s mantle will be modified if partial melting occurs in the transition zone. Melting in the transition zone is plausible if a significant amount of incompatible components is present in Earth’s mantle. We review the experimental data on melting and melt density and conclude that melting is likely under a broad range of conditions, although conditions for dense melt...

Electromagnetic exploration is a geophysical method for examining the Earth's interior through observations of natural or artificial electromagnetic field fluctuations. The method has been in practice for more than 70 years, and 40 years ago it was first applied to ocean areas. During the past few decades, there has been noticeable progress in the methods of instrumentation, data acquisition (o...
