About SIW Calculator (Formula)
The SIW Calculator is designed to calculate the effective cross-sectional area (aeff) for Signal Integrity Waveguides (SIW) based on the provided parameters. The formula for calculating aeff is as follows:
aeff=a−(d2/0.95∗s)
Where:
- eff is the effective cross-sectional area.
- is the distance between two via rows.
- is the diameter of the vias.
- is the distance between two successive vias in the same row.
This formula is used in the context of SIW design to calculate the effective cross-sectional area of the waveguide, which is an important parameter for understanding and analyzing the electrical properties of the waveguide. A larger effective cross-sectional area can lead to lower signal losses and better signal integrity in the SIW structure. The calculator takes these parameters as input and computes the effective cross-sectional area based on the provided values.
