An ultraviolet flux multiplying air sterilization chamber comprises inner surfaces having a diffuse reflective behavior. The sterilization chamber includes an inlet aperture and an outlet aperture for air to flow through said chamber and a light source emitting an ultraviolet light. Due to the reflectivity of the inner surfaces of the chamber, a flux of the ultraviolet light is multiplied by reflecting multiple times from the inner surfaces of the chamber. The inlet and outlet apertures are advantageously configured to reduce the amount of light that escapes from the chamber and increase the amount of photons available in the chamber. In an exemplary embodiment, perforated end panels having diffuse, reflective interior surfaces may be provided over at least a portion of the inlet and outlet apertures.

Methods of drying ink using microwaves includes heating deposited ink droplets by passing a microwave applicator over them. In another embodiment, a swath of ink droplets is deposited with a plurality of sequential passes of an ink jet print head, and the deposited drops are dried between passes.

Microwave energy ink drying method

A microwave applicator suitable for drying sheet material is configured as a dual slot antenna, with one portion of the slot coupled to a wave launching cavity, and the other portion of the slot coupled to an impedance matching cavity.

Microwave applicator for drying sheet material

A microwave ink drying apparatus for an ink jet printer includes a microwave applicator. The applicator may be attached to a movable print carriage. The applicator may further comprise a slot antenna. The slot antenna may be formed as a dual slot, with one portion of the slot coupled to a wave launching cavity, and the other portion of the slot coupled to an impedance matching cavity.
