研究目的
Investigating the optical spectra of a photonic band gap material realized by one-dimensional Triadic-Cantor quasi-periodic structure and the effect of iteration order on its optical properties.
研究成果
The optical performance of the studied systems increases with the iteration order, showing an increase in the widths of the photonic band gaps and their numbers. The presence of optical windows from the 4th iteration is observed, explained by the formation of resonant microcavities in multilayer structures.
研究不足
The study is limited to numerical investigation and does not include experimental validation. The optical properties are analyzed only for normal incidence of light.
1：Experimental Design and Method Selection:
The study uses a trace and antitrace maps approach for the electromagnetic fields to calculate the optical transmission by the quasi-periodic photonic systems.
2：Sample Selection and Data Sources:
The multilayer system is composed of two elementary layers H and L with refractive indices nL =
3：45 (SiO2) and nH = 3 (TiO2), respectively. List of Experimental Equipment and Materials:
The materials used are SiO2 and TiO2 layers.
4：Experimental Procedures and Operational Workflow:
The study involves numerical simulation to investigate the reflection and transmission properties of the multilayer system under quarter wavelength condition.
5：Data Analysis Methods:
The transmission coefficient is calculated using an iterative algorithm based on the trace antitrace method.
