1. An apparatus to detect target materials, comprising:
- an oscillator to generate oscillating THz electromagnetic emission pulses;
an antenna to direct the THz electromagnetic emission pulses towards target materials; and
a detector to detect signature emissions of excited molecules in the target materials;
wherein the target materials do not require sample preparation, and are at a distance of at least 10 meters from the detector.

Abstract
A method and apparatus for remotely detecting, locating, and identifying chemicals and chemical compounds through optically opaque materials. Electromagnetic radiation in the Terahertz range emitted from an antenna array is modulated to excite target molecules. The apparatus then stops the excitation energy and the molecules emit an electromagnetic signature detectable by the device at standoff distances.
