“…Total field satisfies the Helmholtz equation, The boundary conditions for function have the form (8) In the case of a plane wave, the incident field is given by the function (9) Outside the cylinder (at r > a), the total field con sists of incident field U 0 and scattered field U s fields: (10) The scattered field in the far zone must satisfy the radiation condition, (11) where Φ(ϕ) is a scattering pattern.…”

“…NUMERICAL RESULTS All numerical calculations of wave fields were per formed using a modified method of discrete sources [5][6][7], which was previously applied in the study of allied problems [8][9][10][11]. Figure 2 shows a family of curves depicting the dependence of absolute value of the field on dimen sionless parameter ka at coordinates r = a, ϕ = 0 located on the shady side of the cylinder for ε'= -1 and different values of ε''.…”

“…Численное решение сформулированной выше граничной задачи (2), (9) получим методом дискретных источников (МДИ)[7,8]. Точность численных расчетов сформулированной выше задачи рассеяния оценивалась нами путем вычисления невязки  граничных условий: точках контура цилиндра, лежащих по середине между двумя точками коллокации, где невязка достигает своего максимального значения max( )  (т. е. задачи, которая решалась в точках контура цилиндра, лежащих по середине между двумя точками коллокации, где невязка достигает Нормированный поперечник рассеяния структуры при угле падения плоской ТМ поляризованной волны φ0=0 в отсутствии потерь золота 0   = и при радиусе золотого цилиндра a = 50 нм; радиус оболочки из стекла полагался равным: кривая 1b = 60 нм; кривая 2b = 70 нм; кривая 3b = 80 нм; кривая 4b = 90 нм; кривая 5b = 100 нм Рассмотрим сначала случай, когда плоска ТМ поляризованная волна падает на структуру изображенную на рис.…”
