FEKO is a comprehensive electromagnetic simulation software tool, based on state of the art computational electromagnetics (CEM) techniques. It enables users to solve a wide range of electromagnetic problems. The multiple solution techniques available within FEKO make it applicable to a wide range of problems for a large array of industries. Typical applications include:
- Antennas: analysis of horns, microstrip patches, wire antennas, reflector antennas, conformal antennas, broadband antennas, arrays
- Antenna placement: analysis of antenna radiation patterns, radiation hazard zones, etc. with an antenna placed on a large structure, e.g. ship, aircraft, armored car
- EMC: analysis of diverse EMC problems including shielding effectiveness of an enclosure, cable coupling analysis in complex environments, e.g. wiring in a car, radiation hazard analysis
- Bio-electromagnetics: analysis of homogeneous or non-homogeneous bodies, SAR extraction
- RF components: analysis of waveguide structures, e.g. filter, slotted antennas, directional couplers
- 3D EM circuits: analysis of microstrip filters, couplers, inductors, etc.
- Radomes: analysis of multiple dielectric layers in a large structure
- Scattering problems: RCS analysis of large and small structures

TinyOS is an open source, BSD-licensed operating system designed for low-power wireless devices, such as those used in sensor networks, ubiquitous computing, personal area networks, smart buildings, and smart meters. A worldwide community from academia and industry use, develop, and support the operating system as well as its associated tools, averaging 35,000 downloads a year.
OPNET is the industry’s leading network development software. OPNET allows you to design and study communication networks,devices, protocols, and application. It is used by the world’s most prestigious technology organizations to accelerate the R&D process.
Opnet’s object-oriented modeling approach and graphical user interface(GUI) enable relatively easy means of developing models from the actual world network, hardware devices, and protocols. OPNET supports all major network types and technologies, allowing you to design and test various scenarios with reasonable certainty of the output results.
The application areas include:
- Network planning (both LAN and/or WAN) and analysis of performance and problems prior to actual implementation
- Wireless and Satellite communication schemes and protocols
- Microwave and Fiber-optic based Network Management
- Protocol Development and management
- Routing algorithm evaluation for routers, switches, and other connecting devices.
At NRL , we currently use OPNET for teaching and research purposes. Research activities in the area of end system multicasting have been carried out using OPNET’s multicast module. Performance analysis of End System Multicast models have been efficiently carried out.

QualNet is the next generation of the scalable GlMoSim (Global Mobile Information Systems Simulator) simulator. Glomosim was designed to simulate large-scale wireless networks with thousands of mobile nodes, each of which may different communication capabilities via multi-hop ground,aircraft and satellite media. QualNet has extended GloMoSim’s capabilities to wired networks as well as mixed wired and wireless networks. QualNet uses the parallel simulation kernel provided by the PARSEC discrete-event simulation language. Thus QualNet is among the few simulators for wireless and wired networks that been implemented on sequential and parallel architectures.
At NRL , we currently use QualNet for teaching and research purposes. Research activities in the area of mixed-mode simulations are carried out in QualNet.
