Inspired by the Rayleigh backscattering-based sensing methodology on an optical fiber, in this paper, we present a sensing concept based on the random inhomogeneities on a coaxial cable. As an analogy of Rayleigh backscattering along an optical fiber length, “backscattering” also exists from a commercial coaxial cable due to its inherent defects along a cable length which induce a local variation (i.e., impedance mismatch). This is because of the irregular microscopic structures of the inner/outer conductors, and the inhomogeneous density or permittivity of the inner dielectrics after the cables are manufactured. The accumulated backscattered signals along the coaxial cable can be obtained using frequency-domain reflectometry. By analyzing the shift in the local backscattered signal, the local environmental perturbations (e.g., local strain or temperature) can be determined, so that truly distributed sensing capability using a coaxial cable can be achieved. To verify the proposed concept, an intact and commercial coaxial cable was demonstrated for distributed temperature sensing. Compared with the existing coaxial cable-based distributed sensing technologies, the proposed sensing concept does not need extra modifications to the coaxial cable and offers a truly distributed sensing capability.","is_dataset_classified":null,"base_score":2.70805020110221,"endowment":2.70805020110221,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19965766","pmcid":null,"openalex_id":"https://openalex.org/W2910180041","authors":[],"funders":[],"total_grants":0,"fwci":0.8173,"citation_percentile":0.72346055,"influential_citations":0,"citation_trend":[{"year":2019,"count":3},{"year":2020,"count":2},{"year":2021,"count":1},{"year":2022,"count":1},{"year":2023,"count":1},{"year":2024,"count":2},{"year":2025,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":"https://doi.org/10.15223/policy-029","oa_locations":[{"url":"http://xplorestaging.ieee.org/ielx7/19/8863557/08612960.pdf?arnumber=8612960","host_type":"publisher"},{"url":"https://doi.org/10.1109/tim.2018.2890327","host_type":"journal"}],"fields_of_study":["Advanced Fiber Optic Sensors","Analytical Chemistry and Sensors","Photonic and Optical Devices"],"mesh_terms":[],"keywords":["Coaxial cable","Coaxial","Rayleigh scattering","Reflectometry","Materials science","Optical fiber cable","Distributed acoustic sensing","Acoustics","Optical fiber","Backscatter (email)","Electrical conductor","SIGNAL (programming language)","Optics","Fiber optic sensor","Computer science","Electrical engineering","Time domain","Engineering","Telecommunications","Physics","Wireless","Conductor"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-12T01:36:14.962943Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
