Microwave interferometry to elucidate shock properties

摘要

A series of measurements have been performed using a simple, light weight, inexpensive, compact K-Band (SLICK) interferometer to measure the shock properties of passive (Teflon, grout) and energetic (HE) materials. Shock and particle velocity measurements are made simultaneously along the same path. This path is determined by either a thin walled (1/2 mil aluminum foil) waveguide embedded in the material or the caustic of a Teflon axicon. Typically the velocities are determined to about a percent. The measurements will be described and data presented.
