John: A Rayleigh wave is combined with horizontal P wave and vertical S wave. Me: OK. John: The Rayleigh wave move from left to right. At terminal B, when the rayleigh wave is being affected, what will happen? . If (terminal B is affected) { P horizontal wave = compressed. S vertical wave = reflected. } .

One is insertion loss. And, one is reflection loss.  Me: OK. . John: Insertion loss is a real loss.  Me: Why is it real loss? John: Because, part of the power of the signal enter the ground before they enter the inductor. In another words, part of the power of this signal is  attenuated. Me: OK. John: Therefore, the "power" of the signal isn't completely assigned to terminal B.  Me: OK. John: However, is "reflection loss" a real loss? Me: Not really.  John: Why not? Me: Because, the power of the signal completely pass through the inductor. It is only that when the signal is being affected at terminal B, there is a reflection. John: Such reflection isn't a real loss.

John: You might read this article first. https://kamchihau.blogspot.com/2024/12/blog-post.html .  Me: OK. John: That article said "The wider the positive electrodes, the higher capacitance's response and the higher the frequency". Me: Yes,. John: However, it isn't always the case. See the 1st picture. The "ideal" width of the positive electrodes is 6mm. Of course, from 0mm to 6mm, the more close to 6 mm, the higher the response of the capacitance and the higher the frequency. However, if the width of the positive electrodes exceed the ideal width of 6mm, the response of capacitance drop and the frequency drop too. Me: Why? John: See the 2nd picture. The wider the positive electrodes, the deeper the field line. Me: OK. . the width of positive electrodes 0mm (capactiance's response = 0) 2mm (capacitance's response = 2) 4mm (cap...

However, the parallel electrodes disappear. 2) Now, there're fringing electrode formed between (1st 2nd) branch and (3rd 4th) branch. Me: OK. . John: Now, we see the 2nd picture above. There're 2 parts in this picture. They're part of left-hand side and the part of right-hand side. What's the difference between them? . 1) At the part of the left-hand side, there's a fringing electrodes.

Me: The clock line comes from the center-tap.  The clock line just "cover" the register of Port A.  The clock line never "cover" the "Overflow-area".  Therefore, Stack-overflow can't occur. Me: The principles of hacking isn't "Stack overflow". John: The overfow-area is at mask-interrupt. Me: Read this articles. ( https://wodewangzhishime.blogspot.com/2023/12/sequential-99.html ) .
