The authors describe initial experiments employing 5.5 GHz pulsed microwave power, which should result in enhanced chemistry compared to present state-of-the-art plasma aftertreatments by; reducing plasma electric field shielding, increasing availability of atomic nitrogen, exploiting surface charging of dielectrics, avoiding (low field) threshold initiated discharges, and achieving a higher high energy tail on the electron distribution function. As an example, the authors decided to test for NO reduction in N{sub 2}. While this reaction is not a complete description of the exhaust issues by any means, they thought it would demonstrate the technology proposed.
