MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122909 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Dec. 5, 2025, for 'system for modeling underwater optical communication channels with microplastic scattering effects.'
Inventor(s) include Dr. Poongundran Selvaprabhu; M Sakthi Sorna Maheswar; Pradeep K; and Thalirmahizhan D.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a system for modeling underwater optical communication channels with microplastic scattering effects. The system includes a signal generation module (101, 102, 103, 104) configured to generate optical communication signals for underwater transmission, a channel modeling module (106) configured to incorporate microplastic-induced scattering effects calculated using Mie scattering theory, an input configured to receive microplastic particle concentration data, and an analysis module (110, 111) configured to calculate transmission performance metrics based on the channel modeling incorporating the microplastic-induced scattering effects. The signal generation module includes a PRBS generator (101), an NRZ pulse generator (102), a continuous wave laser (103), and a Mach-Zehnder modulator (104). The system incorporates baseline water attenuation characteristics with microplastic-induced scattering effects to simulate realistic underwater optical channels across different water types and pollution levels."
