<radio communications> ability of electromagnetic waves to propagate into or through materials

OBS

Non-conducting materials are essentially transparent to electromagnetic waves, but absorption mechanisms, particularly at higher frequencies, reduce the amount of energy propagating through the material.

OBS

Metals constitute good reflectors for freely propagating electromagnetic waves, with very little of an incident wave being able to propagate into the metal surface.

OBS

Low-frequency tagging systems are said to have good penetrative properties as their tag can be read when behind or encased in other materials.

OBS

Microwave tagging systems, while having greater ranges, are less capable of penetration of materials.

OBS

penetration: term and definition standardized by ISO/IEC [ISO/IEC 19762-4:2008].
