Resonant heating

Textiles. Microwave drying of textiles is under investigation, in addition to the possible uses for curing of impregnated and dyed fabrics (182). A microwave clothes dryer for consumer or commercial apphcation is also under discussion (183). Considerable developmental work and media pubhcity have occurred. Problems remain, however, particularly relating to arcing and resonant heating of metal objects that may be present in a load of clothes. These problems may be alleviated by operation at 915 rather than 2450 MHz (184).

Fig. 3) This figure exhibits radiation induced magneto-resistance oscillations at/ = 360 GHz. Note that fast oscillations, which are due to the Shubnikov-de Haas effect, are superimposed on the slow radiation induced component. Cyclotron resonance heating is visible as noise at Bj ...

It is then in an excited state E of the adsorption potential from which it can cascade down to the state i = 0, emitting more phonons and thus heating up the solid. This process is called resonant heating.
