Founder & CEO

  • ISRO, 1979–80
  • DRDO, 1980–present
  • Indian missile programme
  • SEMCEI life member

SGOI is led by an engineer who helped build India's electromagnetic compatibility capability from the inside. He spearheaded EMI/EMC test facilities in three DRDO laboratories, and was one of the main members in establishing six further EMI/EMC centres across public sector undertakings and private organisations.

EMC = Science + Technology & Fixes. All are equal to EMI. The SGOI approach

EMC is needed right from design and breadboard model through to the developed model, in its required environment. EMI/EMC purely follows natural phenomena: avoid interruptions in the natural flow of current, and it will not bother anyone.

Awareness of EMC is a must for design engineers, scientists, production agencies, inspection agencies, test laboratories, technicians, and scientific and technical assistants.
