It’s October 7th.

Two years ago, I would’ve described myself as progressive. That day showed me I was standing on the side of people that are truly evil.

I really held two contradictory views from being in the movement. I’ve heard all these things about Israel abusing the Palestinians and I believed them. I also had seen antisemitism growing up in Mississippi and felt very strongly it was something decent people should fight.

And so I did what almost no other progressive did in the aftermath of October 7th. I took time to really read and study the conflict before voicing opinions on it. And it turned out everything the progressive movement has been claiming the Israelis were doing was just frankly a lie. Six wars and six major conflicts since 1948, and Jews had started none of it. The constant barrage of rocket attacks on civilians truly shocked my conscience, something none of my friends seemed to care about.

In the two years since that horrific day and progressives have been crystal clear. Jews don’t count. And since I decided to stand with them, they’ve made it clear that I don’t count either.

It has been like setting my career and friendships on fire. I regret literally nothing because that inch of integrity is all we have in this world. But I do regret standing for so long with a movement fundamentally, incapable from telling good from evil.

Okay let's look at this filter and make some observations:

1. It consists of 5 separate bowtie resonators. This tells me it is a 5th-order filter, meaning that it has 5 'poles'.

2. The resonators are different sizes, with the largest in the middle, and the smallest at the ends. They are roughly symmetric.

3. The resonators are twisted relative to each other in an alternating pattern. This is the key to your question. More later.

4. The 'squiggly line' is always perpendicular to the bowties (except curiously the first), and the intervals are all of equal length.

Explanation:

Let's start with just a single bowtie. You get a basic filter with one 'pole'. A 'pole' is a point of resonance in the complex plane in Laplace space, roughly corresponding to frequency and phase. This is roughly your basic Butteworth filter

Now we go to 5 exactly similar bowtie resonators, and then you get 5 poles separated by the phase length of the wire between them. This could be 5th order Butterworth if the poles are all real-part negative, or a relatively boring Chebyshev if they are spaced equally around the unit circle.

Now we change the size of the resonators like you see in the circuit, large in the middle, and small at the ends. Now we are stretching the poles into an oval pattern. This is the classic Chebyshev filter.

Now we tilt the resonators toward each other in alternating fashion as you observe. We are creating coupling between the poles, which shifts them closer to each other in one phase, and further apart in the opposite phase. Absolute wildness. John Belushi just crashed the party. Now we have to use an elliptic function to describe the transfer function, and so this is called an elliptic filter.

Why? Because we want a very strong frequency drop-off, and we're willing to accept a few side-lobes. But then again, there is still the mystery of the first resonator, and maybe there is some magic in that element.

But to get back to your question specifically about the squiggles, it's to allow the resonators to tilt relative to each other, and hopefully I've explained why that is relevant.

Note: This was entirely human-typed, and it's been 20 years since I took a class in Analog, so assume some mistakes and inapt terminology. I 'm probably not the best person in the world to answer this question, but I didn't see any strong responses yet, so I guess I'm all you've got.

#WLPC Phoenix 2025 will be remembered for ever as the pinnacle of nurture in our community. I owe a lot to @keithparsons and the community for a life changing event. I had to write about it and share this story.

#Aaronia is the coolest spectrum analyzer you can have. It was one of the best deep dives I have attended at #WLPC. @MackenzieWiFi and the @aaronia_AG team @HB9FXQ did an excellent job of showcasing its capabilities.
