Mutual-Inductance Computation between Coaxial Thin Conical Sheet Inductor and the Circular Loop in Air

“…2023, 13, x FOR PEER REVIEW 2 of 23 special case of this new developed formula is the formula for calculating the mutual inductance between the cylindrical solenoid and the filamentary circular loop, the practical applications of the previous mentioned configuration could be interesting in many domains of electromagnetics such as the excitation coil used in electromagnetic-levitation melting, the production of magnetic field homogeneity and the high magnetic field under the cone, which can be used to magnetize a magnetic sheet [10][11][12][13]. The calculation of the previously mentioned coils is useful for conical inductors which are of ideal form for ultrabroadband applications up to 40 GHz since the conical shapes limit the effects of stray capacitances and effectively substitute a series of narrow-band inductors, creating the high impedance over a very wide bandwidth and in wireless power transfer systems that utilize conical inductors [14][15][16][17][18][19][20][21][22][23][24]. In all cases, either the regular or the singular are explained with precise explications.…”
