Calculation of Accurate Resistance and Inductance for Complex Magnetic Coils Using the Finite-Difference Time-Domain Technique for Electromagnetics

An Eulerian MHD model for the analysis of magnetic flux compression by expanding diamagnetic fusion plasma sphere

“…The advection equation for radial direction is obtained by dropping axial terms from Eq. (16). The solution update is as given by Eq.…”

“…For MFC problems with imperfectly known boundary conditions, complex geometries and materials having large variations in electrical conductivity (materials from insulator to conductor); the finite difference time-domain (FDTD) method for electromagnetics [15][16][17][18] may be the best suited method to calculate the amplified field in the compression volume and the diffused magnetic flux into the liner. This method can be coupled to a suitable hydrodynamic algorithm to obtain the evolution of density, pressure, temperature, etc.…”

“…Detailed discussions on the advantages and disadvantages of such approach are given in Refs. [15][16][17][18] (also, see Refs. therein).…”

Comprehensive Analysis of Octapole Electromagnetic Launcher

“…The use of electromagnetic field to produce the propulsive force is beneficial to overcome the velocity and hazardous limitations of chemical launchers [1], [7]- [10]. Multipole Electromagnetic Launchers has the potential of developing huge thrust force, large driven mass, super velocity launch and steady maglev [2]- [6].…”

Finite difference time domain algorithm for electromagnetic problems involving material movement

“…A detailed description of the application of FDTD method for such systems and its advantage over conventional methods is available in our earlier work [11][12][13]. Those studies were, however, limited to static conductors.…”
