Abstract: Described is a system for producing a three-dimensional (3D) printed radio frequency (RF) absorber. The system includes a computer configured to produce a computer model and a 3D printer. The 3D printer has an extruder controlled by a motor directed by the computer to deposit melted plastic filament loaded with a RF absorber material in computer controlled patterns according to the computer model to produce a RF absorber having a custom profile of desired RF absorption properties and desired dielectric properties.

Abstract: Described is a method for manufacturing a radio frequency (RF) absorber. The method includes first determining a set of desired RF absorption properties for a RF absorber. A computer model for the RF absorber having the determined set of desired RF absorption properties is then produced. Using a three-dimensional (3D) printing process, melted plastic filament loaded with a RF absorber material is deposited in in computer controlled patterns according to the computer model, thereby producing the RF absorber having the set of desired RF absorption properties.

Abstract: Described is a method and system for producing a three-dimensional (3D) structure using 3D printing. A 3D structure, having multiple regions, is produced using a 3D printer having at least one extruder formed to receive a printer filament. The printer filament has at least one type of material having radio frequency (RF) absorption properties. The RF absorption properties are varied at different regions of the 3D structure by varying the extrusion of the at least one type of material at different regions of the 3D structure.

Abstract: Described is an electrode-less plasma lamp comprising a gas-fill vessel, a gas-fill contained within the gas-fill vessel, an RF electromagnetic radiation source, an RF electromagnetic resonator, an output probe that couples RF energy from the RF electromagnetic resonator to the gas-fill vessel, an input probe that couples RF energy from the RF electromagnetic radiation source to the resonator, and a grounding strap that holds a metal veneer surrounding the resonator and a portion of the gas-fill vessel at RF ground. Also described are many variations of the electrode-less plasma lamp; non-limiting examples of which include embodiments that employ other probes in a Dielectric Resonant Oscillator to drive the lamp, and many methods of improving light-harvesting, including raising the gas-fill vessel away from the resonator via a coaxial type transmission line, and collecting light with an optical reflector.

Abstract: Described is a plasma electrode-less lamp. The device comprises an electromagnetic resonator and an electromagnetic radiation source conductively connected with the electromagnetic resonator. The device further comprises a pair of field probes, the field probes conductively connected with the electromagnetic resonator. A gas-fill vessel is formed from a closed, transparent body, forming a cavity. The gas-fill vessel is not contiguous with (detached from) the electromagnetic resonator and is capacitively coupled with the field probes. The gas-fill vessel further contains a gas within the cavity, whereby the gas is induced to emit light when electromagnetic radiation from the electromagnetic radiation source resonates inside the electromagnetic resonator, the electromagnetic resonator capacitively coupling the electromagnetic radiation to the gas, which becomes a plasma and emits light.
