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

EMP Analysis of a Building

An analysis of electromagnetic pulse radiation in indoor environments. Introduction Behaviour and propagation of electromagnetic fields in indoor environments are relevant to a range of technologies including through-wall radar devices, shielding of critical equipment in hospitals and the analysis of … Read More

Log Periodic Dipole Array

A log-periodic dipole array is modeled in FEKO to determine input impedance and radiation patterns Log-periodic dipole arrays (LPDAs) are wideband structures having a geometry such that its impedance and radiation characteristics vary periodically with the logarithm of frequency. This … Read More

Dielectric Resonator Waveguide Filter

An evanescent-mode waveguide filter consisting of two parallel cutoff waveguide paths with dielectrics is modeled in FEKO and compared with results from the open literature. The authors of [1] describe an evanescent-mode waveguide filter consisting of two parallel cut-off waveguide paths … Read More

Intelligent Design with Characteristic Mode Analysis

This white paper illustrate the benefits of CMA for antenna design and integration. The theory of Characteristic Mode Analysis (CMA) is a well-known method originally proposed by Garbacz [1] and later refined by Harrington and Mautz [2] that allows for … Read More
