Abstract :
An idealized two-dimensional model of modified concentric loop for focused electromagnetic heating of limbs and torsos is considered. In contrast to the uniform current excitation, the scheme has two current nulls diametrically opposite to one another. In this case, the circumferential electric field dose not vanish on the axis, which overcomes the principal criticism of the uniform loop
