Apparatuses, systems, and methods for heating a fluid or other material. The apparatuses may include a container (e.g., tube) in which a susceptor material is disposed. The susceptor material may convert microwave energy to heat, which may increase the temperature of a fluid or material in or adjacent the tube.

An electromagnetic heater for heating an irregularly shaped object, including: a cavity within which an object is to be placed; at least one feed which feeds UHF or microwave energy into the cavity; and a controller that controls one or more characteristics of the cavity or energy to assure that the UHF or microwave energy is deposited uniformly in the object within ±30% over at least 80% of the volume of the object.

An applicator for thermal treatment of a product in which the product is exposed to electromagnetic microwave radiation in an exposure waveguide, in which the microwaves are coupled and propagate according to a single-mode propagation mode. The applicator includes a system for transporting the product in a continuous flow following the longitudinal direction of the cavity of the exposure waveguide between the inlet opening and the outlet opening. A product treatment device includes at least one applicator and at least one continuous wave generator CW. The product, heated by continuous microwave radiation CW in device, is subjected to a thermal treatment method in line with a temperature curve as a function of time, resulting in particular from a speed of movement of the product in the exposure waveguide and from a power of the microwave radiation coupled into the exposure waveguide at each coupling point.

A method of forming a microwave applicator comprising forming a body comprising dielectric material so that there is a void in the dielectric material, and depositing conductive material in the void to form a feed for coupling energy into the dielectric material.
