ABSTRACT:
A method and apparatus for heating fluids is disclosed. One or more receptacles for holding fluids are located in an interior cavity formed by an exterior conductive surface. In one embodiment, the receptacles are spaced from a side of the exterior conductive surface a distance equal to an odd multiple of 1/4 of a wavelength. In another embodiment, bases of the receptacles are spaced a distance equal to slightly less than an odd multiple of 1/4 of a wavelength from the bottom of the exterior conductive surface. In a further embodiment, a receptacle has a pointed base for enhancing the heating of fluids. Furthermore, receptacles can be formed with bases spaced an odd multiple of 1/4 of a wavelength from at least two adjacent sides of the exterior conductive surface. Receptacles can be formed in a platform that may be made to fit into preexisting electromagnetic heating chambers.
