Strategies and Design Space

The design space for a SMM/THz sensor is very large. Accordingly it must be bounded by some interaction of scientific and technical limits with requirement specifications. In this case we sought to have a complete sensor packaged within a 1 ft³ (28 L) box that was able to identify the components in a mixture of more than 30 gases with very high specificity. For a portion of these gases it was desired to be able to detect them at a concentration of 100 ppt or less.
