Abstract (en)

[origin: WO9948336A1] A method for microwave heating as well as a microwave oven therefor. The heating of a load with low effective relative permittivity epsilon is carried out utilising a resonant quarterwave mode, which in the case of high epsilon preferably becomes a Brewster mode, or vice versa. In a preferred embodiment, the resonant quarterwave mode is combined with an additional mode, preferably a Brewster mode, so that a quadrature field pattern is obtained at the load.
