Abstract
The shielding effectiveness (SE) of materials strongly depends on the exciting field characteristics, polarization, angle of incidence, wave impedance. In real life situations building walls are excited in a random way, making this very similar to what happens inside an electromagnetic reverberation chamber (RC). The paper describes how to measure the SE inside an RC to replicate this real life situation. In particular, cementitious composites are characterized because directly useful for the construction of building walls. The method is based on the using of a nested chamber where the sample is inserted, located inside a larger one to randomly excite the sample. Results are presented for different concentration of concrete filling materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
