FDTD

This is a dataset of Finite Difference Time Domain (FDTD) simulation results of 13 defective crystals and one non-defective crystal.  There are 4 fields in the dataset, namely: Real, Img, Int, and Attribute. The header real shows a real part of the simulated result, img shows the imaginary part, int gives the intensity all in superimposed form. Attribute denotes the label of a crystal simulated. The label 0 is for the simulated crystal, which is non-defective.  Other 13 labels, from crystal 1 to crystal 13 are assigned to the 13 different crystals whose simulations are studied.

The geomagnetic disturbances create large-scale geo-magnetically induced currents (GICs) in long conductors at the Earth's surface. The GIC might cause hazard to many infrastructures, out of which, the electrical transmission lines located at the vicinity of ocean is the prime example. The unique physics behind this phenomena lies at the sharp contrast in the electrical conductivity between ocean and continent.

The geomagnetic disturbances caused during the solar storms create large-scale geo-magnetically induced currents (GICs) in long conductors at the Earth's surface. The GIC might cause hazard to the electrical transmission lines located at the vicinity of ocean. The unique physics behind this phenomena lies at the sharp contrast in the electrical conductivity between ocean and continent. Though analytical methods were used previously to study electromagnetic fields at ocean-continent boundaries, those were only limited for highly simplified geometries and sinusoidal sources.
