Adaptive Band Synthesis (ABS) - A Video Introduction
Adaptive Band Synthesis (ABS) (Microwaves & RF: May 2002)
The ABS technique combines minimal
adaptive EM frequency simulation with a highly accurate proprietary
interpolation technique to provide 200-400 data points. The ABS data sweep
requires significantly less time than conventional techniques and yields much
higher data resolution.
Conformal Mesh - A Video Introduction
Conformal Mesh - For Efficient Planar Electromagnetic Analysis
Sonnet's radical Conformal Mesh technique forms large subsections that follow the arbitrarily
curving edges of a complicated circuit while still inherently including the high
edge current. Using such conformal subsections, non-Manhattan, curving
geometries can be analyzed efficiently and accurately.

Calibration Errors - Potentially Significant On-Wafer High Frequency Measurement
Calibration Error
This article addresses a specific case of a spiral inductor on silicon for which
there was a significant difference between measurement data and analysis data
and concludes that the problem is with the measurement. A new method of
"synthetic calibration" is described that can be used with any EM analysis to
quantify calibration error for any proposed set of calibration standards.

Perfectly Calibrated Internal Ports in EM Analysis of Planar Circuits
Perfectly calibrated internal ports have
recently been developed for high frequency electromagnetic
analysis of planar circuits. This capability has never before
been available. As such, microwave designers are only just
now learning the value of such ports. This overview paper
describes new and extremely efficient design methodologies
that are now practical. For example, if properly prepared, an
entire circuit can be EM (electromagnetically) analyzed once
and the precise analysis of all subsequent modifications
(tuning, tweaking) of the circuit provided essentially
instantly. Another capability enabled by perfectly calibrated
ports is compact model synthesis. These capabilities are
illustrated with examples.
Deembedding the Effect of a Local Ground Plane
in Electromagnetic Analysis
In electromagnetic analysis of complex planar circuits,
it may be necessary to use internal ports, e.g., in locations
where surface mount devices might later be attached. These
internal ports require a local ground plane for ground reference
when access to the global ground reference is unavailable. Even if
perfectly conducting, use of such a ground plane still introduces
excess phase in the local ground currents. This paper describes
how to remove the effect of a lossy or lossless local ground, even
including multiple closely spaced ports.
