Microwave Testing (MW)
Method Overview
High-frequency electromagnetic technique scanning composite and ceramic structures for internal voids, delamination, and moisture.
Core Method Specifications
Target Applications & Governing Standards
1 Scopes ConfiguredMethod Limitations & Operational Boundary Conditions
Critical physics limits, thermal envelopes, blind spots, and ASME Sec V / API procedural boundaries for MW.
Dielectric loss tangent of polymers shifts with temperature, affecting microwave phase measurement.
Horn antenna near-field standoff required (typically 10 mm to 50 mm)
None (air-coupled microwave transmission)
Microwave electric field vector should align with joint fusion plane for electrofusion fittings
- •Conductive metallic materials: Microwave radiation reflects 100% off metals; completely blind to internal defects in steel, aluminum, or copper
- •Water films on exterior surface absorb microwave energy, blinding the receiver
