Did you know that adding a thin plating of good conductor on badly conductive material in RF transmission line can have lower loss at RF than trace made fully of either material by itself? Thought this was a bug in my solver at first, but it's a real physical effect.

It’s unbelievable that a spectrum analyzer costs that much money.

Browser based 2D field solver I've been writing for a while is now up. It calculates characteristic impedance and losses for many common and less common transmission lines.

For decades, electronics offered 2 levels of routing structure to manage signals that originate or terminate in an IC. Recently, that number has risen to 5, bringing greater complexity and design decisions

An Explosion In Interconnect Complexity
The chip industry has gone from two routing platforms to five. That's a lot.

I've been writing online transmission line field solver for a while. It will calculate impedance and loss for many PCB transmission lines. Supports solder mask, S-parameter export and more. Missing just last polishing and testing.

This is how a 1.33 uF 600 V 450 A looks like. Take a look at the SMD 1206 capacitor at the top left corner for comparison.
