The "ART" of Waves

There are three scientific phenomena that occur as electromagnetic waves encounter a material:

• Absorption
  Energy loss as electromagnetic waves pass through. This energy loss is usually converted to thermal energy. Absorption is highly dependent on the thickness and magnetic properties of the shield.


• Reflection
  Energy reflection when electromagnetic waves encounter a material. Reflection can occur from both the front and back surfaces and within the material, independent of the materials thickness.


• Transmission
  Energy passing through a material with minimal disturbance.
