ABSTRACT:
A diesel particulate filter including a microwave-absorbing target housed within a waveguide cavity lined along the walls with a hard-electromagnetic surface (HES). The HES modifies specific electromagnetic boundary conditions for a given design frequency so as to enable the establishment of electromagnetic field patterns which are more uniform across the cavity thereby causing the target material to undergo enhanced uniformity heating. The heating of the microwave absorbing media causes particulate buildup to be vaporized and removed from the filter by the exhaust stream flow.
