“…It still assumes that the fundamental field inside the sphere is a plane wave of constant amplitude, but undergoes a phase shift as it goes through the second half of the sphere [15]. Recently, a systematic experimental investigation of SH scattering as a function of size parameter was conducted with polystyrene spheres [16]. The trend observed experimentally agreed well with the predictions of the nonlinear Mie scattering theory and, also, with the nonlinear Wentzel-Kramers-Brillouin model.…”

“…Such a configuration poses many challenges, an important one being the ability to implement a phase matching or quasi-phase matching mechanism in order that the contribution from each round trip of the light beam would add coherently with the contribution from the previous one. As opposed to a small sphere, where phase matching within the sphere plays a little or no role at all [16], a high-Q cavity-enhanced interaction demands a phase matching or quasi-phase matching mechanism. Further challenges arise if a pulsed operation is considered, such as a group velocity dispersion that would quickly lead to a walk-off between the fundamental and SH waves.…”

“…На настоящий момент имеется три наиболее используемых модели: модель Релея-Ганса-Дебая [8][9][10], модель на основе точного решения задачи о рассеянии [11,12] и модель Вентцеля-Крамерса-Бриллюэна [13]. Первая модель применима при малых размерах исследуемых систем и не учитывает рассеяние на границах раздела, однако для нее проще всего получить аналитическое решение.…”

“…Со-поставляя полученное пространственное распределение с предсказанным теоретической моделью, можно оце-нить значения коэффициентов анизотропии для иссле-дуемой поверхности. Поскольку зачастую нелинейные свойства частицы обусловлены свойствами адсорбиро-ванного на ее поверхности красителя [2][3][4][5][6][7], то зна-ние коэффициентов анизотропии позволяет определить поверхностную плотность адсорбированного вещества, свободную энергию [8], ориентацию молекул красителя на поверхности [9] и другие свойства. …”
