You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Simulations : The optical response was simulated of cavity systems using Comsol Multiphysics with the Wave Optics module , using a p - polarized plane wave as the source with normal incidence . A 2D periodic model with a period of 300 nm and a symmetric mesh with a maximum size of 40 nm was used . The refractive index data for T34bT were taken from the experimental ellipsometric determination .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
