New Way of Generating Electromagnetic Waves

The Permanent Magnet Based Reluctance Modulated VLF Transmitter: An Equivalent Circuit Analysis

“…The proposed transmitter [4], depicted in Fig. 1, makes use of a permanent magnet (PM) with an intrinsically high magnetic moment, capable of producing a static magnetic flux without the use of external energy.…”

“…This method shows how to convert a geometrical description of magnetic devices (coils, magnetic materials, and permanent magnets) into a circuit description. This paper investigates the MEC of the new permanent magnet-based transmitter introduced in [4,5]. The transmitter generates a time-variant field by modulating the magnetic reluctance of the medium surrounding a permanent magnet.…”

“…The transmitter generates a time-variant field by modulating the magnetic reluctance of the medium surrounding a permanent magnet. The transmitter employs a multiphysics approach to simultaneously incorporate certain electromagnetismmagnetism concepts to demonstrate the feasibility of the idea [4], which requires further investigation to comprehend and advance its architecture. Also, we show how the MEC analysis of this transmitter assisted us in developing its potential performance.…”

New Approach on Generating Electromagnetic Waves for Transcranial Magnetic Stimulation

“…The U-shape permanent magnet is employed to imitate the overall performance of the figure-8 coil since the figure-8 coil is more focal than other types of coils. The system operates in two modes, similar to the concept described in [5,6]. The magnetic film (with thinner thickness) in front of the permanent magnet poles is deeply saturated by the magnet and allows the magnetic flux to pass through it.…”

“…This paper presents an alternative approach to stimulate neurons using the modulated magnetic flux of a permanent magnet. In [5,6], we exploit a permanent magnet, equivalent to a lossless electromagnet with a superconductor winding, to produce a static magnetic flux without dissipating power. Meanwhile, we modulate the reluctance of the flux path to take an alternative path to make it time-variant.…”
