1. A system comprising:
a container configured to hold one or more items contaminated with a contaminant;
a power amplifier configured to output radio frequency (RF) energy at a frequency substantially equal to a resonant frequency of the contaminant;
a horn connected to the power amplifier and configured to propagate the RF energy along a length of the container and through the one or more items to deactivate, damage, or destroy the contaminant by molecular resonance; and
an RF absorbing liner disposed on interior surfaces of the container and configured to absorb and reduce reflection of at least some of the RF energy;
wherein at least one of a thickness of the RF absorbing liner or a material of the RF absorbing liner is selected to achieve a substantially uniform cross-sectional power density of the RF energy.
