Theses ultra short pulses are produced using three transmission lines and two switches that induce electric current through Micro coil. The technique is based on time-resolved magneto-optic Faraday effect in a (Bi:YIG) film. A unique feature of the method is that it directly measures the ultra short magnetic pulses with spatial resolution in order of micrometer. M3 ER -
