    Calculation methods are presented for the reflection and transmission spectrum of the ultrasonic waves incident from the fluid onto the general anisotropic solid layer. It is found that the sound reflection and transmission coefficients depend on the media parameters, orientation and thickness of the solid layer, incident angle and sound wave frequency.

Plasma-Polymerized organic film starting from thiophene has been prepared. The elemental composition of pristine film was determined by elastic recoil detection (ERD) and Rutherford backscattering spectrum (RBS). FT-IR technique has been used to characterize the sample film. From the near-IR to UV reflectance and transmittance data, we calculated the optical constants of the film, N(ω) = n + ik ,by using the transfer matrix method.

Plasma-Polymerized organic film starting from thiophene has been prepared. The elemental composition of pristine film was determined by elastic recoil detection (ERD) and Rutherford backscattering spectrum (RBS). FT-IR technique has been used to characterize the sample film. From the near-IR to UV reflectance and transmittance data, we calculated the optical constants of the film, N(ω) = n + ik ,by using the transfer matrix method. In view of the calculations, we investigated the optical properties of the pristine in detail. Moreover, the doping effect in the plasma-polymerized thiophene film with 24 keV I+ implantation has been also explored. The result shows that the transport process of charge carrier in bombarded layer can be interpreted by Mott's VRH model.

The absorption coefficient of solid film is an important quantity. Bouguer Lamberts law is only valid for internal transmittance where no interface effect presents. The correct value on absorption coefficient of film in a pile can be obtained according to the calculation of optical constants by using transfer matrix method from the reflectance and transmittance spectra. According to this method, the absorption coefficients of plasma polymerized pyrrole film (two layer structure) and its 100 keV Ar + irradiated layer (a pile of three layers) have been calculated by us elsewhere. In this communication, we compare it with that obtained from Bouguer Lamberts law to evaluate the error resulting from interfaces.

固体膜对光的吸收系数是一个重要的物理量,布格尔-朗伯(Bouguer-Lambert)定律仅适用于无界面影响的内透射情况。从光的反射和透射谱,运用传递矩阵方法,通过光学常数的计算,可以得到吸收系数的正确值。文中将由此得到的等离子体吡咯聚合膜(双层结构)及其100keVAr+辐照层(三层结构)的吸收系数与由布格尔-朗伯定律直接得到的值进行比较,以了解由界面引起的误差。

The plasma - polymerized pyrrole film is irradiated by I+ ion beam of an energy of 2 0 keV at a fluence of 1 × 1016 cm"2 . The conductivity of the I+ implanted surface layer could be increased by 11 orders of magnitude. From the near - IR to UV reflectance and transmittance spectra, by using the transfer matrix method, we obtain the complex refractive indices of the pristine film and I+ implanted layer. On the basis of the optical studies, the information of the energy loss function is also available.
