The suitability of holographic structures fabricated in zeolite nanoparticle-polymer composite materials for gas sensing applications has been investigated. Theoretical modeling of the sensor response (i.e., change in hologram readout due to a change in refractive index modulation or thickness as a result of gas adsorption) of different sensor designs was carried out using the Raman-Nath theory and Kogelnik's coupled wave theory. The influence of a range of parameters on the sensitivity of holographically recorded surface and volume photonic structures has been studied, namely, hologram geometry, hologram thickness and spatial frequency, reconstruction wavelength, and zeolite nanoparticle refractive index. From this, the optimum fabrication conditions for both surface and volume holographic gas sensor designs have been identified. Here in Part II, results from modeling of the influence of design on the sensor response of holographically recorded volume grating structures for gas sensing applications are reported.
已对在沸石纳米颗粒 - 聚合物复合材料中制造的全息结构用于气体传感应用的适用性进行了研究。使用拉曼 - 纳特理论和科格尔尼克耦合波理论对不同传感器设计的传感器响应（即由于气体吸附导致折射率调制或厚度变化而引起的全息图读出变化）进行了理论建模。研究了一系列参数对全息记录的表面和体光子结构灵敏度的影响，即全息图几何形状、全息图厚度和空间频率、重建波长以及沸石纳米颗粒折射率。据此，确定了表面和体全息气体传感器设计的最佳制造条件。在第二部分中，报告了关于设计对用于气体传感应用的全息记录体光栅结构的传感器响应影响的建模结果。
