He has made significant contributions to the field of engineering, particularly in the development of advanced materials and evaluation methods for structural integrity. With a total of 2 patents, his work showcases a blend of creativity and technical expertise.
Latest Patents
Li Wei's latest patents include a Germanium telluride-based reflectarray element and a millimeter-wave frequency-reconfigurable reflectarray antenna. The reflectarray antenna consists of multiple reflectarray elements, a dielectric substrate, a metal ground, and a feed source. The reflectarray element is strategically placed on the upper surface of the dielectric substrate and features a loop body along with two phase delay lines. Notably, two first germanium telluride films are embedded within the loop body, effectively dividing it into two equal-length segments. Each segment connects to the middle portion of one phase delay line, while two second germanium telluride films are symmetrically distributed around the phase delay line's center.
Another significant patent is an evaluation method for corrosion damage evolution of underwater concrete structures. This method involves conducting a time reversal test on a concrete beam specimen submerged in water, alongside uniaxial compression tests on concrete cube specimens. The specimens are immersed in hydrochloric acid, and the time reversal tests are performed on specified days to assess the corrosion evolution process without damaging the underwater concrete structure.
