The Fourier Integral Transform and its high-performance digital counterpart, the Fast Fourier Transform, are two of the key heritage tools used in scientific and engineering data spectrum analysis. The Fourier Transform and its high-performance digital counterpart, the Fourier Transform, are one of the main heritage tools used in scientific and engineering data spectrum analysis. The Fourier's assessment of nonlinear mechanics that have existed for a long time and the associated FFT make some a-priori assumption about the source data, such as linearity and being stationary.

Critical information that enables successful satellite and spacecraft operations is shared from space-to-ground radio frequency radio frequency radio frequencies, enabling safe satellite and spacecraft operations. Link performance and reliability could be enhanced if radio frequency interference could be detected and minimized in an automated manner. To improve communication efficiency, researchers from the NASA Glenn Research Center created a software-based automated RFI mitigation device to increase communication speed after discovering unexpected interference events during space-to-ground communications.

The RFID Tag with Long Range and Wide Coverage Capabilities at the NASA Johnson Space Center has developed a variety of RFID technologies targeted at inventory control and reporting devices, one of which is the RFID Tag with Long Range and Wide Coverage Capabilities. These RFID tags can be used to create new applications in a variety of industries thanks to their dual benefits of long range and broad coverage made available by retroreflection.

In the aftermath of recent developments that have reduced fan and jet noises to overall jet-engine noise, aircraft manufacturers are shifting their attention toward minimising engine core noise. In subsonic jet engines, the CMC acoustic liner has variable-depth channels tuned to minimize broad-spectrum noise. The oxide/oxide CMC materials are also resistant to high temperatures. To minimize engine core noise, these CMC acoustic liners can be used in several subsonic jet engines, particularly for next-generation aircraft. In addition, core liners made with CMC materials can also provide a thermal barrier because they can withstand high temperatures.

NASA has created a new optical fiber that is suitable for solar lighting applications and electric generation. Fiber solar cells' performance and functionality are unsurpassed by both the performance and functionality of traditional flat-panel solar cells. A hybrid solar energy cell device made from this new optical fiber may have three or four layers of glass, including a mixture of n-type nanowires and selected p-type polymers. First, the amount of visible light sent to the lighting application can be adjusted by selecting the fiber content.

A number of RFID tags have been created by researchers at the NASA Johnson Space Center, aimed at improving communication with an RFID reader with a larger number of RFID tags in open and enclosed areas. The Agile RFID Antenna System can be extended these boundaries by adding an inexpensive frequency multiplexer to the RFID reader antennas, which allows new methods of localization, and increases antenna coverage with fewer reader RF ports, as well as improved read quality and/or range.

By incorporating a differential linear Fresnel lens into an imaging chip, NASA's Langley Research Center's Langley Research Center has developed a very small spectrometer. NASA is using the lens/chip in a very small spectrometer that will be mounted on a rover's tires to check soil on the moon or Mars. Since Fresnel imaging results as valid focal points of spectrum within the short optical distance, the shorter optical path length allows for the small size. The conversion to a differentially linear Fresnel lens saves the need for aperture slit driver electronics and moving parts, as well as eased manufacturing.
