WebThe wave velocity (vp), the angular frequency (ω) and the wave number (k) are related as vp = ω/k = nλ. Let the wave velocity in the medium to which the wave is transmitted be v’p = ω/k´ = nλ’. If second medium is denser, in comparison to first medium (i.e. μ2 > μ1), then from Snell’s law. ⇒ k1 < k2 and λ1 > λ2. WebOct 31, 2013 · An intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings is proposed and experimentally demonstrated. The sensor is formed by a tilted-fiber Bragg grating (TFBG) coated by magnetic fluid (MF) and cascaded by a chirped-fiber Bragg grating (CFBG). Transmission of the TFBG is modulated by refractive index of …
