Industry Context.
Aerospace and defence platforms operate in some of the most demanding electromagnetic environments in service. From high-intensity radiated fields (HIRF) near airports and naval radars to lightning strikes at altitude, aircraft and defence systems must maintain full electrical and electronic function under extreme conditions. Increasingly, composite airframes, dense avionics packaging, and multi-domain operations are compounding the EM challenge. Regulatory frameworks – DO-160, MIL-STD-461/464, and RTCA standards – demand rigorous verification. The cost of late-stage EMC failures in these programmes, in both time and certification risk, makes early simulation-based analysis not just valuable but essential.
We hold active membership in the SAE ARP AE2/AE4 working groups for HIRF and Lightning standards – the same bodies that shape the certification requirements our clients must meet. Our team has direct programme experience across multiple platforms working within Indian military certification frameworks. We deploy high-fidelity tools to deliver analysis-backed compliance evidence from the earliest design phase.

Platform-level High-Intensity Radiated Field Assessment
Full-platform HIRF analysis per MIL-STD-464 and DO-160 — assessing electromagnetic threats including field penetration and coupling into aircraft systems. Outputs include shielding effectiveness maps, harness coupling predictions, and certification-ready reports.
Lightning Transient Analysis on Aircraft Wiring & Avionics
Model lightning indirect effects per DO-160 and MIL-STD-464, predicting induced transients on wiring and avionics for metal and composite airframes. Our outputs define pin level currents/voltages and guide protection design, ensuring a traceable path from lightning threat to verified system protection.
Optimising RF Performance Across Multi-Antenna Platforms
Full-wave EM simulation evaluates installed antenna radiation patterns, inter-antenna isolation, and co-site interference risks across fixed-wing, rotary-wing, and UAV platforms. Antenna placement is optimised for gain, coverage, and isolation within structural and aerodynamic constraints – preventing mission degradation from mutual coupling.
Radar Cross Section Assessment and Signature Reduction
Monostatic and bistatic RCS analysis identifying high-scatter contributors, with low-observable design support through shaping, RAM guidance, and cavity treatments. Outputs include RCS plots, contributor breakdowns, and design recommendations – integrated with HIRF and IEL work for consistent signature management.
Bridging Lab Test and Computational Analysis
Pre-test prediction and post-test correlation for MIL-STD-461 and DO-160 EMC testing – using simulation to reduce test failures and enable rapid root-cause analysis. Accelerates certification timelines and strengthens airworthiness submissions under certification frameworks.
