Modelling Magnetic Resonance Imaging (MRI)

An application note on the modelling of MRI in FEKO. Introduction EM simulation involves the numerical approximation of Maxwell’s equations to determine the EM behaviour of detectors and radiating structures. No physical assumptions are made regarding the fields when using … Read More

reflector model

Crossed Dipole Array in Front of Reflector

A crossed dipole array with metallic reflector is modeled in FEKO to determine its gain pattern. In mobile communication systems the position and orientation of the receiving and transmitting antennas change continually. This can affect the signal strength at the receiver, … Read More

Thermal Analysis for Implant Safety

The number of people with medical implants, such as pacemakers, replacement for various joints and monitoring devices are increasing steadily. At the same time, more and more people undergo MRI examinations for diagnostic purposes. During an MRI scan, strong RF … Read More

Shunt Coupled Spiral Inductor

A spiral inductor on a substrate is simulated in a shunt configuration and its S-parameters extracted. This article presents FEKO simulations that are representative of RF components that are constructed on a dielectric.  The model that is simulated here is … Read More

Four-Port Microstrip Coupler

A four-port microstrip coupler is modelled in FEKO to calculate its transmission, coupling and isolation Schwab and Menzel described the design of microwave components using planar multilayer structures in [1].  One of the structures described in this work is the … Read More
