The speaker gave a brief overview about associated IEEE society\, chapter along with her professional journ ey.\n\nFollowing things were presented in this talk:\nThe rapid growth in global data traffic driven by emerging applications such as 6G communicati ons\, holographic telepresence\, and ultra-high-resolution video streaming (16K/32K) is pushing existing wireless and wired infrastructures toward t heir capacity limits. While the Terahertz (THz) spectrum offers a promisin g solution to address this demand\, the widespread deployment of fiber-opt ic networks remains constrained by high capital expenditure and infrastruc ture rollout challenges. Consequently\, exploring alternative high-capacit y transmission solutions that leverage existing infrastructure has become increasingly important.\n\nThis presentation investigated the feasibility of Terabit Digital Subscriber Line (TDSL) technology\, which aims to utili ze existing twisted-pair copper cabling for ultra-high-speed data transmis sion in the sub-THz regime. Specifically\, the study evaluates the potenti al of metallic waveguide-based transmission structures operating in the D- band (100–300 GHz) to support terabit-per-second data rates.\n\nTwo prim ary transmission configurations are examined: (i) circular hollow waveguid es designed to emulate the air channels within CAT6 cables\, and (ii) copp er wire waveguides consisting of two-wire and four-wire structures\, imple mented in both bare-metal and dielectric-coated configurations. The resear ch methodology integrates full-wave electromagnetic simulations using CST Microwave Studio\, experimental characterization using Terahertz Time-Doma in Spectroscopy (THz-TDS)\, and analytical channel modeling implemented in MATLAB.\n\nThe results indicate that dielectric coating on copper wires s ignificantly improves electromagnetic field confinement\, leading to incre ased surface current density and stronger electric field coupling between conductors compared with bare-wire configurations. These findings highligh t the strong potential of metallic sub-THz waveguide-based transmission fo r enabling ultra-high-speed short-range data links. With continued advance ments in THz device technologies and coupling mechanisms\, Terabit DSL cou ld provide a practical and cost-effective pathway toward future beyond-5G and 6G broadband access networks.\n\nThe talk was concluded at 6:30 PM IST with a Q&A session of 10 minutes\, in which audience interacted with the speaker.\n\nSpeaker(s): Prof. Fauziahanim Che Seman\, \n\nVirtual: https:/ /events.vtools.ieee.org/m/553666 LOCATION:Virtual: https://events.vtools.ieee.org/m/553666 ORGANIZER:IEEE.apmtts.sbciitkgp@gmail.com SEQUENCE:12 SUMMARY:Terabit DSL over Copper: Exploring Sub-THz Waveguide Transmission f or Future 6G Networks URL;VALUE=URI:https://events.vtools.ieee.org/m/553666 X-ALT-DESC:Description: <br /><div style="text-align: justify\;"><span styl e="font-family: arial\, sans-serif\;">The talk "Terabit DSL over Copper: E xploring Sub-THz Waveguide Transmission for Future 6G Networks" started wi th a brief introduction of the speaker\, Dr. Fauziahanim Che Seman.
