A group of Iowa State University researchers has successfully demonstrated a photonic bandgap filter that can operate in the far-IR region of the spectrum. According to Gary Tuttle, who is an electrical and computer engineering professor at the university, the filter will give astronomers more of the desired light while rejecting unwanted light. Although other filters have similar capabilities, the new filters could prove less expensive. They could be used for several applications, including certain microwave devices, cell phones, radar antennas, global positioning systems and high-efficiency...Read full articleRelated content from Photonics MediaArticlesFlow Cytometry Technique Shows Promise for Early Cancer DiagnosisA digital droplet microfluidic flow cytometry technique could enable earlier recognition of tumor development and progress, by aiding in the detection of multiple microRNAs (miRNAs) in single...BioPhotonics Nov/Dec 2022 IssueNanoresonator for 6G Enhances THz Waves 30,000-FoldThe swift development of 6G communications using terahertz (THz) electromagnetic waves has intensified the demand for highly sensitive nanoresonators that can detect these waves.
