EM Material Analyzer: RF & Microwave Material Characterization Software

A high-fidelity electromagnetic material extraction suite for RF engineers, researchers, and lab environments. Compute complex real and imaginary permittivity (ε', ε''), magnetic permeability (μ', μ''), and plane-wave shielding effectiveness directly from Vector Network Analyzer (VNA) scattering parameters.

Comprehensive Technical Capabilities

Broadband Solvers

Simultaneous wideband extraction algorithms for complex permittivity (ε) and magnetic permeability (μ).

  • Nicolson-Ross-Weir (NRW): Standard transmission/reflection method for scattering parameters.
  • Non-Iterative Method: Fast, stable permittivity extraction that completely eliminates phase-unwrapping errors.
  • NIST Iterative Root Finder: High-precision iterative framework optimized for thick samples and low-loss materials.
  • Short Circuit Line (SCL) 1-Port: Dedicated reflection-only measurement model for tight spaces or metallic backings.

Fixture & De-Embedding

Mathematical compensation for hardware tolerances, sample placement, and calibration boundaries.

  • Transmission Line Support: Coaxial lines, rectangular rectangular waveguides, and free-space propagation modes.
  • Automated Air-Gap Correction: Analytical compensation for sample-to-holder boundary tolerances.
  • Analytical Port Extensions: Phase shifting to mathematically adjust reference measurement planes.
  • Touchstone Fixture De-embedding: Dynamic subtraction of test fixtures using standard (.s2p) data files.

Resonant Method Analytics

High-precision extraction modules tailored for narrow-band, single-frequency high-Q systems.

  • Resonant Cavity Perturbation: Precise extraction for small solid dielectric samples based on frequency shift and Q-factor change.
  • Open-Ended Coaxial Probe: Mathematical models optimized for liquid, semi-solid, and biological material characterization.
  • Q-Factor Processing: Advanced geometric peak-fitting engine for high-loss and low-loss resonance lines.

EMI Shielding (IEEE 299)

Direct parsing of plane-wave Shielding Effectiveness parameters from measured transmission and reflection S-values.

  • Total Shielding Effectiveness (SE): Overall attenuation calculation expressed clearly in decibels (dB).
  • Absorption Loss Analysis: Isolation of energy dissipation inside the physical material matrix.
  • Reflection Loss Analysis: Computation of raw return losses at the front material boundary.
  • Multiple Reflection Correction: Full compensation for internal resonance inside thin-film shields.

Advanced Data Visualization

Interactive rendering of complex dielectric, magnetic, and conductive parameters across the RF spectrum.

  • Permittivity Profiles: Real (ε') and Imaginary (ε'') components plotted over custom sweeps.
  • Permeability Profiles: Real (μ') and Imaginary (μ'') magnetic attributes.
  • Dielectric Conductivity (σ): Calculated frequency-dependent loss characteristics.
  • Loss Tangents: Dedicated curves for Dielectric (tan δe) and Magnetic (tan δm) dissipation.

Batch Automation & Export

Accelerate laboratory data extraction pipelines with bulk actions and publication-ready outputs.

  • Batch Queue Processing: Drag-and-drop workflow to convert folders of raw VNA files simultaneously.
  • Excel (.xlsx) Export: Well-structured spreadsheets containing fully calculated values alongside raw data arrays.
  • Automated Report Layouts: Export directly to formatted sheets with embedded high-resolution vector plots.
