An explosion simulation system for simulating blast effects of an explosive device includes a transmitting device connected to the explosive device to transmit a virtual radio frequency blast wave upon activation; and attenuate the virtual radio frequency blast wave to match a mass of explosives used in the explosive device. The system also includes remote receiving devices comprising an audible alarm to indicate when the blast wave is received from the transmitting device. The receiving devices may get activated upon receiving the blast wave; calculate one or more effects of a blast of the explosive device by decoding the blast wave based on an explosive charge weight comprising a kg TNT equivalent of the explosive device, a distance, a peak incident pressure, a peak reflected pressure, and a peak reflected impulse; and display the effects of the blast in at least one category comprising an ear rupture threshold.

The present invention relates to systems and methods for modifying or amplifying explosive devices through electromagnetic radiation (EMR). Exemplary embodiments provide increased energy density to an explosive reaction zone to allow increased blast overpressures, detonation velocity, and energy release without changing the explosive materials or quantity of explosives. An exemplary embodiment irradiates a reaction zone immediately before an explosive detonates to modify the explosive properties of an explosive device. Exemplary embodiments utilize automated targeting of EMR sources for precise modification of explosions with standardized and predictable effects.

The invention relates to sealable short-pathlength liquid transmission cells for Fourier-transform infrared spectroscopy applications. In exemplary embodiments, a liquid transmission cell with transmissions sections uses horizontal tubing for inserting and removing fluids from the cell. Angling the tubing relative to a top face of the cell allows small amounts of entrapped air to rise out of the optical path without blocking spectroscopy measurements. The tubing is silver-soldered to the body of the transmission cell to make a leak-free connection.
