Abstract: A microwave applicator for heating a moving fluid includes a heating chamber having a fluid inlet and a fluid outlet and through which the fluid to be heated flows. The applicator also includes a microwave energy source and a microwave circuit having at least one wave-guide element. The microwave circuit transforms microwave energy from the microwave source into a cylindrical wave-guide mode within the heating chamber for uniformly heating fluid flowing through the heating chamber. This technology is also applied as a method for applying microwave energy for heating a moving fluid. This method includes passing a fluid from a fluid inlet, through a heating chamber, and out a fluid outlet; and applying a microwave energy source through a microwave circuit including at least one wave-guide element to transform microwave energy from the microwave energy source into a cylindrical wave-guide mode within the heating chamber to uniformly heat the fluid flowing through the heating chamber.
