Abstract

The invention relates to a capacitor with changeable dielectric properties, and a device for electric pulse modulation comprising such a capacitor, for instance an HPM source (High-Power Microwave, high-power microwave radiation). The invention is shown as a capacitor comprising two electrodes (1, 2) spaced from each other by a dielectric (3) comprising an explosive. When the explosive detonates/has detonated, it gives rise to residual products (4) with new dielectric properties. The permittivity of the residual gases is lower than that of the explosive. Depending on the field of application, the electric conductivity of the residual gases is either good or poor. Poor conductivity means that the reduced permittivity gives a voltage amplification across the capacitor. Good conductivity means that the residual gas is short circuited, thus resulting in a voltage reduction across the capacitor.
