The divider assembly of claim 1, wherein the gasket is electrically conductive so as to electrically couple the metal frame to the metal walls of the microwave oven.3. The divider assembly of claim 1, wherein the gasket comprises a high temperature silicon tube around which the small-diameter, long-length carbon nano-tubes are formed.4. The divider assembly of claim 1, wherein the small-diameter, long-length carbon nano-tubes are single-walled carbon nano-tubes.5. The divider assembly of claim 1, wherein the small-diameter, long-length carbon nano-tubes are multi-walled carbon nano-tubes.6. The divider assembly of claim 1, wherein the small-diameter, long-length carbon nano-tubes are formed from a hexagonal lattice of carbon atoms.7. The divider assembly of claim 6, wherein the hexagonal lattice of carbon atoms is capped by fullerene-like structures.8. The divider assembly of claim 1, and further comprising at least one foot extending downward from a surface of the metal frame for engaging at least one shelf ledge that extends from the inner walls of the microwave oven.9. The divider assembly of claim 1, and further comprising a tin-oxide coating on a surface of one of the first and second tempered glass panels.10. The divider assembly of claim 9, wherein the tin-oxide coating is disposed on a surface of the second tempered glass panel.11. An electromagnetic cooking device comprising:an enclosed cavity;the divider assembly of claim 1 disposed within the enclosed cavity so as to divide the enclosed cavity into a first subcavity and a second subcavity;at least one first microwave source for generating microwave energy within the first subcavity to cook food disposed therein; andat least one second microwave source for generating microwave energy within the second subcavity to cook food disposed therein.12.
