PENGARUH INDUKSI MEDAN RADIO FREQENCY (RF) PADA DIPOL-DIPOL MOLEKUL AIR
ABSTRACT: The non-linear
optical property of rotary power of light polarization in water has been
develop using the Radio-Freguency field (RF-Field). The RF-Field used in the
experiment is produced by RF generator, and it supplies the frequency in the
range betwen 6,04 to 14,56 MHz which then applies to the samples. The source of
light with 632,8 nm-wavelength and 532 nm-wavelength are used to observe the
change of range polarization of the light after it passes througt the
samples. Three modes of the direction of
the electric field of light are chosen 0o (E//) (E of light is parallel to E of
RF-Field), and 90o (E ) (E of light is perpendicular to E of the RF-Field) in
order to determinate the optimal change of the angle of the polarization β. The
values of β is measured as a function of RF-Field, , where ωRF is the angular frequency of
RF-Field and BRF is the magnitude of
magnetic field measured in the center of the coil which is assumed to be
homogeny in the circumstances of the samples. The results of the experiment
show that the degrees of change of the polarization direction, η is largest at
the E3 mode. It shows also that at small wavelength of light we obtain the
larger η, which is indicated the higher frequency of liglt will more induce the
dipoles of molecules of the samples.
