Title: HEMP Modification from Secondary Electron Inertia

Abstract

We describe a modification to the standard analysis of high frequency electromagnetic pulse (HEMP) that treats the inertia of the secondary electrons. We calculate the radiating HEMP field for an instantaneous gamma source in an idealized geometry with and without inertia. Inertia makes a significant correction to the signal if $$\mathcal{V_{en}T_{P}}$$ < ~0.1 where $$\mathcal{V_{en}}$$ is the electron-neutral collision frequency and $$\mathcal{T_{P}}$$ is the time when the peak radiating HEMP field is reached in the collisionless limit.
