Combined 3D electromagnetic and spin response simulation of MRI systems

MRI-Whitepaper thumb

Modern MRI systems are highly complex devices, and the interaction between the body and MRI coils introduces additional challenges into the design process. The body, with its complicated heterogeneous interior, causes major disturbance to the homogeneity of the magnetic fields, while energy absorbed by the body can cause harmful heating. Experimental measurement of these effects is often impossible, but simulation with 3D body models can help the engineer identify risks to the patient and suggest ways to reduce them.

Whitepaper - Photonic Crystal Cavities

CST Whitepaper Photonic 100 This whitepaper gives a general overview on different concepts of photonic crystal cavities. Important figures such as the transmission, the mode volume and the quality factor are discussed. The presented information will help the reader to decide which type of photonic crystal cavities will be most suited for the application in view. A design example for a WDM channel filter is given in order to illustrate the design process for a photonic crystal cavity. Furthermore two experimental examples from recent research are shown to demonstrate the wide range of applications in which photonic crystal cavities could be used. 詳細下載..

Whitepaper - Matching circuit optimization for antenna applications

matching- Impedance matching is an essential part of antenna design. The input impedance of an antenna needs to be reasonably close to the amplifier impedance (e.g. 50 Ohm), otherwise the signal is reflected back to the amplifier and not radiated by the antenna. In many applications matching circuits consisting of discrete inductors and capacitors, or transmission lines are used to improve the impedance matching characteristics of the antenna. This white paper discusses the optimization of matching circuits especially to antenna applications. Although the design of matching circuits sounds simple, there are many practical considerations that need to be addressed. 詳細下載..

Whitepaper - Installed Performance of Communication Antenna Arrays

installed The presence of multiple communication antennas on a tower means that antennas may have to be installed in sub-optimal positions. Electromagnetic simulation can be used to design the antennas themselves, and also to optimise the positioning of the antennas on the tower. This article will describe how multiple solvers in CST MICROWAVE STUDIO® can be combined to predict where to install an omnidirectional stacked bicone antenna array to minimise loss of omnidirectionality. 詳細下載..

Whitepaper - Optimization of a Reflector Antenna System

antenna- In this paper a modular approach using the so-called System Assembly and Modeling (SAM) of CST STUDIO SUITE® is used to optimize a reflector antenna system in a piecewise manner. The results are compared to a full system simulation. It is shown that a similar accuracy to that of the full system simulation can be attained with the modular approach with a much shorter simulation time and using less computational resources. 詳細下載..
