Electronics Masterclass

We’re so glad you’re here.

This forum was created just for you—to build on what you’ve learned in Transmission Lines 101 and to keep the conversation going. While we created the space, it belongs entirely to you—our growing community of curious, committed design engineers.

Here, you can connect with fellow engineers, share insights, ask questions, and most importantly, continue learning together. Got a transmission line question for Dr. Eric Bogatin? Post it here! Each month, we’ll gather your top questions and record a video Q&A with Eric to help take your understanding even deeper.

Over the years, I’ve seen firsthand how powerful it is when engineers come together in a spirit of generosity and curiosity. So let’s make this a space that reflects the best of our profession—where respectful, meaningful dialogue leads to real growth.

We’ll moderate the forum to ensure it stays a constructive and inspiring environment, in alignment with…

In Transmission Lines 101 by Prof. Eric Bogatin, is Jsurf of the HFSS simulation on page 14 of the slide overlayed on the surface of dielectric, copper of the return layer, copper of the signal layer, or all of the above?

I want to make the pretty picture like that as well.
