With a total of two patents to his name, his work has implications for various applications, including satellite technology.
Latest Patents
One of his latest patents is for a high emissivity article that features multiple layers of high-performance materials. This article is designed for use in man-made satellites, providing high emissivity and low reflectance in the thermal infrared wavebands between 6 and 30 microns, as well as in the visible wavebands. The article serves to protect individual solar cells from ionizing radiation and micro-meteoroids, while also safeguarding the adhesive bonding from UV light. It effectively maintains the solar cell at a relatively low temperature due to its excellent emissivity in thermal waveband regions. The design incorporates a glass substrate with a high emissivity coating made up of alternating layers of dysprosium fluoride and silicon oxide, along with an anti-reflection coating of erbium oxide and dysprosium fluoride.
Another significant patent by Jones is an interference filter, also known as a notch filter. This filter reflects specific wavelength ranges while allowing other wavelengths to pass through. It is designed for operation in both the visual and infrared regions of the electromagnetic spectrum. The filter utilizes uniform layer pairs of materials, with each layer's optical thickness being a non-quarter-wave unequal thickness relative to its complementary layer. This innovative design maintains a half-wave optical thickness throughout the layer pair, even on curved surface substrates.
