Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
They require a starting current pulse to operate, usually supplied by capacitors. Explosively pumped flux compression generators are used to create ultrahigh magnetic fields in physics and materials science research [1] and extremely intense pulses of electric current for pulsed power applications.
Pulsed-power water treatment is the process of using pulsed, electro-magnetic fields into cooling water to control scaling, biological growth, and corrosion. The process does not require the use of chemicals and helps eliminate environmental and health issues associated with the use and life-cycle management of chemicals used to treat water. [ 1 ]
Pulsed electromagnetic field therapy (PEMFT, or PEMF therapy), also known as low field magnetic stimulation (LFMS) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression. [1] By 2007 the FDA had cleared several such stimulation devices. [2]
Energy is typically stored as electric potential energy within capacitors, or in the case of explosive pulsed power, as chemical energy.The stored energy is released over a very short time scale resulting in a large amount of power being delivered to a load which can be used to study high energy density physics phenomena such as Inertial confinement fusion using a Z-pinch, and plasma physics ...
The spectral shear is typically generated by sum-frequency mixing the test pulse with two different quasi-monochromatic frequencies (usually derived by chirping a copy of the pulse itself), although it can also be achieved by spectral filtering or even with linear electro-optic modulators for picosecond pulses.

A pulsed field magnet is a strong electromagnet which is powered by a brief pulse of electric current through its windings rather than a continuous current, producing a brief but strong pulse of magnetic field. Pulsed field magnets are used in research in fields such as materials science to study the effect of strong magnetic fields, since they ...
