Ka-Band Shielding at 40 GHz The Ka-band spectrum is driving the next generation of communication systems. From 5G infrastructure to satellite ground stations and advanced defense radar, applications operating between 26.5 and 40 GHz demand unprecedented signal integrity. At 40 GHz, wavelengths shrink to 7.5 millimeters — a scale where conventional shielding approaches expose criticalRead More
Radiated vs. Conducted EMI Nothing fails a qualification test faster than a leaky gasket or an unfiltered power cord. For defense contractors and engineering teams, a failed MIL-STD-461 test means schedule delays, budget overruns and the frustration of rework. EMI is often treated as one monolithic problem, but the reality is more complex. When evaluatingRead More
Waveguide-Below-Cutoff Vents: Balancing Airflow and EMI Shielding in High-Security Enclosures Cooling high-security enclosures creates an engineering conflict. High-performance electronics require massive airflow to prevent thermal failure. However, standard ventilation methods, like louvers or perforated panels, act as wide-open doors for radio frequency (RF) leakage. For systems mandated to meet NSA 94-106 RF shielded enclosure spec/testingRead More
NEMA Type 6 Meets EMI/RFI Whether you're in the defense space or a private industry such as energy or mining, protecting your valuable and sensitive equipment is vital. This includes combating water, dust and impact damage. A NEMA Type 6 enclosure can help with this. But when your equipment is at risk of electromagnetic interferenceRead More
Understanding MIL-STD-461Defense electronics operate in some of the most electromagnetically hostile environments on the planet. Avionics in fighter jets, communication arrays on naval vessels and radar systems at ground bases must operate reliably despite constant exposure to interference. For defense contractors and engineering teams, MIL-STD-461 compliance determines whether equipment in these applications meets the requirementsRead More
SMR Enclosures: Protecting the Future of Nuclear Energy Small modular reactors (SMRs) are setting a new standard for the nuclear energy industry. These compact, factory-produced units offer flexible and rapid deployment compared to traditional large-scale plants that require decades to construct. However, achieving this shift requires rethinking how containment enclosures protect the entire system. UnderstandingRead More
Case Study: Thermal Threats in Dubai A clear example is found in the INNOVIA APM 300 automated people-mover at Dubai International Airport. Equipto was tasked with protecting control system electronics in a sealed NEMA 3R-rated enclosure, where ambient temperatures regularly reached 118°F (47.9°C). Combined with solar gain and the absence of natural airflow, the riskRead More
Why EMI/RFI Shielding Isn't Optional Anymore in Modern Electronics In an era defined by spectrum saturation, contested electromagnetic environments, and near-peer adversary capabilities, electromagnetic interference (EMI) and radio frequency interference (RFI) are no longer secondary design concerns — they are existential threats to system reliability. The increasing density of components, the ubiquity of wireless communications,Read More
