Semtex-H Simulant: Terahertz Absorption Coefficients for Security Screening

ASCII data for measured and calculated absorption coefficients associated with a paper on developing a safe explosive simulant. The data was collected or modeled as part of research at the University of Leeds to create non-hazardous mixtures mimicking Semtex-H's terahertz spectral features. It supports the testing of security screening systems without requiring real explosives.

Use Cases

• Validating terahertz spectroscopy instruments based on simulated explosive spectral data mentioned in the description
• Training or testing genetic algorithm models for material composition selection as described in the associated paper
• Benchmarking the performance of security screening systems against safe simulant signatures
• Analyzing the spectral similarity between proposed organic compound mixtures and a target explosive

Strengths

• Data is directly associated with a published academic paper, providing methodological context.
• Focuses on a specific, applied problem in security screening using terahertz frequencies.
• Proposes four concrete simulant mixtures for instrument testing, as stated in the description.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
