Abstract :
Novel varistor materials based on ALD surface modified metal particles embedded in a polymeric binder were found to display exceptional non-ohmic electrical properties. Sub- nanosecond transient response times with negligible overshoot and low capacitance, leakage current, and insertion loss were repeatedly observed. These properties enable these novel devices capable of suppressing fast rise-time transients induced by electromagnetic pulse (EMP) and high-power magnetic weapons (HPM).
