“…By comparison, microwave heating has a high heating rate and energy efficiency [18]- [22], and has no limitation on part shapes, as energy is applied to the part (component) by an electromagnetic field [23], [24] [24]. For example, rapid energy-efficient heating of carbon fiber reinforced polymer composite laminates was realized by Zhou et al [25], where an improvement of 36.3 times in heating efficiency and a reduction of 99.2% in energy consumption were achieved, compared with conventional autoclaves.…”

Heating plays a vital role in various manufacturing processes of metallic products. Microwave heating has many advantages over conventional conductive heating methods whilst it is currently limited to heating dielectric materials and powdered metals. This paper reports a new microwave heating method using electromagnetic resonators, which was, for the first time, proved effective for heating solid metals. This is a quite promising discovery, because as known, solid metals are essentially reflective of microwaves, and thus metallic objects are often prohibited in microwave ovens. The experiment results showed almost complete microwave absorption and excellent heating performance for a range of metal plates including both magnetic (e.g., iron, nickel and invar) and non-magnetic (e.g., tin and zinc). A patterned microwave heating process was also presented by adjusting electromagnetic resonators and microwave radiations. On this basis, a new multi-zone microwave processing paradigm was developed and demonstrated for welding metal plates. The research work may not only provide potential solutions for efficient heating and processing of complex shaped metal parts, but also enable a plethora of applications like localized heating and thermal display.
