Focus, Far and Near Fields
Educational funk-rock fusion, Electric bass plays syncopated sixteenth-note slap patterns, Clean electric guitar performs rhythmic scratching and staccato chords, Drum kit maintains a tight backbeat with open hi-hat accents, Male vocals deliver rhythmic, instructional lyrics in a mid-range tenor, Analog synthesizer leads provide melodic flourishes between vocal phrases, Tempo is 115 BPM in the key of G major, 4/4 time signature
[Intro] [slap bass, clean electric guitar scratching, tight drum kit] [Verse 1] [male vocals] Fresnel zone, intensity varies wild But at the focal point baby, that's where beams get styled Natural focus distance equals D squared over 4L Best lateral resolution lives at this location [analog synth flourish] [Chorus] The beam is widest at the transducer face Narrows at the focus, that special place Then diverges in the far field, Fraunhofer zone Lateral resolution deteriorates as we've grown Aperture controls the beam width near Frequency affects the far field deer Electronic focusing, phased array Modern scanners focus all the way
