A method is presented to investigate diffraction of an electromagnetic plane wave by an infinitely thin infinitely conducting circular cylinder with longitudinal slots. It is based on the use of the combined boundary conditions method that consists of expressing the continuity of the tangential components of both the electric and the magnetic fields in a single equation. This method proves to be very efficient for this kind of problem and leads to fast numerical codes. The scattering matrix that is obtained from this theory can then be used in a multiscattering method to study wave propagation in square arrays of such resonators with an emphasis on the low-frequency behavior.
本文提出了一种研究具有纵向狭缝的无限薄无限导电圆柱对电磁平面波的衍射方法。它基于组合边界条件法，该方法包括在一个单一方程中表示电场和磁场切向分量的连续性。这种方法被证明对于这类问题非常有效，并能得到快速的数值代码。从该理论得到的散射矩阵随后可用于多散射方法，以研究此类谐振器方形阵列中的波传播，重点是低频行为。
