“…Finally, Bessel beams have been recently proposed also for TMS treatm consist of particular solutions to Maxwell's equations, particularly useful in applications thanks to the peculiar nature to not suffer diffractive propagation coherent with increasing distances. Rotundo S. et al [81] proposed this physi by implementing an innovative radiating system for TMS. Moreover, the hard tion is composed of five concentric planar spiral coils, working at typical TMS singularly and appropriately fed with proper current amplitude and phase.…”

In recent years, the usage of radio frequency magnetic fields for biomedical applications has increased exponentially. Several diagnostic and therapeutic methodologies exploit this physical entity such as, for instance, magnetic resonance imaging, hyperthermia with magnetic nanoparticles and transcranial magnetic stimulation. Within this framework, the magnetic field focusing and shaping, at different depths inside the tissue, emerges as one of the most important challenges from a technological point of view, since it is highly desirable for improving the effectiveness of clinical methodologies. In this review paper, we will first report some of the biomedical practices employing radio frequency magnetic fields, that appear most promising in clinical settings, explaining the underneath physical principles and operative procedures. Specifically, we direct the interest toward hyperthermia with magnetic nanoparticles and transcranial magnetic stimulation, together with a brief mention of magnetic resonance imaging. Additionally, we deeply review the technological solutions that have appeared so far in the literature to shape and control the radio frequency magnetic field distribution within biological tissues, highlighting human applications. In particular, volume and surface coils, together with the recent raise of metamaterials and metasurfaces will be reported. The present review manuscript can be useful to fill the actual gap in the literature and to serve as a guide for the physicians and engineers working in these fields.

“…Magnetic field plays a vital role when treating maligns and cancer [9] , tumors [10] , drug targeting [11] , cell separation [12] , magnetic endoscopy [13] and adjusting blood flow during surgery [14] . Behavior of blood flow and temperature is essential to be studied in more controlled environment during such processes.…”
