I want you to act as an academician. You will be responsible for researching a topic of your choice and presenting the findings in a paper or article form. Your task is to identify reliable sources, such as Google Scholar, organize the material in a well-structured way and document it accurately with citations. My suggestion request is writing an original academic paper more than 10000 words named ‘Bandwidth broadening and complex coupled structure design of membrane-type acoustic metamaterials for low-frequency sound absorption’. Provide the entire answer in JSON format.
