Web24 apr. 2024 · The study found that mmWaves altered bacteria growth, mainly depressing their growth and changing certain properties and activities. Bacteria and other cells might communicate with each other by high-frequency fields in the mmWave region, thus creating the observed impacts when exposed to mmWaves. Web1 mrt. 2011 · For future body-centric applications, it is particularly important to assess the effect of clothing on the millimeter-wave absorption. The dielectric constant of clothing ɛ c has never been investigated at 60 GHz. Here we assumed ɛ c = 1.25 + j 0.024; this corresponds to the complex permittivity of the dry fleece at microwave frequencies [ 21 ].
