High Speed Hard Disk Suspension Electric Design and Model Validation
In a hard disk drive for magnetic data storage, successful design of the front-end R/W channel is vital for achieving high density storage. Such a design involves both high track densities with resultant smaller signals and higher linear densities with signals occupying wider frequency bands. Current technical literature offers few works describing the design process, and there is no consensus as to choosing either time-domain characterization or the frequency-domain (S-parameters) modeling approach.
Simulation of Cold-Test Parameters for Slow-Wave Structure using Eigenmode Solver
Cold-test parameters of a slow-wave structure can be obtained using CST MICROWAVE STUDIO® (CST MWS) Eigenmode solver without considering the input and output couplers. A single period helical slow-wave structure is simulated in the Eigenmode solver with...
Optical Ring Coupler Simulation
CST MICROWAVE STUDIO® (CST MWS) lends itself well to the simulation of optical devices since it easily handles electrically large problems. In this case, an optical ring coupler with a substrate dimension of 20 by 25 wavelengths is simulated.
Optimization of a 10-Way Conical Power Combiner
This article describes the use of CST MICROWAVE STUDIO® (CST MWS) in simulating and optimizing a 10-way conical transmission line power combiner operating at X-band (6-14 GHz). This device is an example of an axially symmetric power combiner, commonly...
Optimization of Torque in a Permanent Magnet Synchronous Motor (PMSM) for Traction Applications
