Summary

Based on an international gathering of scientists and engineers from 17 countries, this book, the fifth in a continuing series, assesses microwave processing of materials as an emerging technology. Significant advances in understanding and control of microwave energy and its use in the processing and testing of materials are outlined. Future research and development needs are also explored. Topics include: scale-up and commercialization; microwave nondestructive testing; microwave processing; microwave system design; dielectric properties measurements and analysis; modelling of microwave heating; microwave interactions and mechanisms; microwave processing using variable frequency sources; alternate microwave sources; remediation of hazardous waste; temperature modelling and measurements; microwave processing of polymers; and plasma processing.
