Topband: Modeling the proverbial "vertical on a beach"

[Dan Maguire via Topband]

The latest AutoEZ update includes the ability to create EZNEC models having 2 separate ground media.  One typical use is to model a vertical located on a sandy beach next to salt water.

Using AutoEZ you can assign a variable to the media 2 linear boundary and then run a series of test cases with different values for the boundary coordinate.  Here is an animation of how the pattern for a 20m quarter-wave vertical changes as the distance to the water is varied from 0 to 100 feet.
