Latest Patents

One of Long Zhang's latest patents is titled "Method for Reflective Index Modulation Based on Intelligent Reflecting Surface." This method introduces an IRS control unit into wireless communication systems. The data to be transmitted is divided into reflective domain data and phase-amplitude domain data. The reflective domain data is transmitted through a wired connection to the IRS control unit, which activates or deactivates groups of reflecting elements. The phase-amplitude domain data is modulated through traditional methods and transmitted to the IRS. The reflected signals contain information from the reflective domain data, allowing for the recovery of both phase-amplitude and reflective domain data.

Another notable patent is the "Method for Preparing Novel Waterborne Polyurethane Foam Layer for Synthetic Leather." This method involves preparing charged cellulose nanofibers from wood pulp. It also includes a series of reactions involving polyisocyanate and macromolecular diols to create a cationic or anionic waterborne polyurethane. The charged cellulose nanofibers are combined with the ionic waterborne polyurethane emulsion, leading to the formation of a stable Pickering foam. This foam serves as a template for creating a waterborne polyurethane foam layer suitable for synthetic leather.
