The low frequency band
SpletMentioning: 54 - We present an accurate methodology for representing the physics of waves, in periodic structures, through effective properties for a replacement bulk medium: this is valid even for media with zero-frequency stop bands and where high-frequency phenomena dominate. Since the work of Lord Rayleigh in 1892, low-frequency (or quasi … Splet\$\begingroup\$ If you're talking about radio signals, the quote is probably referring to the fact that there's a lot of man-made noise in that frequency band, primarily harmonics of …
