OMG the best idiotic line ever
for god sake, scientists are designing a 5th gen fighter, not designing next Hollywood Transformer movie kits``! please cut of these noncensical craps so to make your posts are a bit more creditable`thx
The joke is on you, and what is up with 'OMG' you sound like a 13 year old girl gossiping over a boyfriend. The sawthooth edges, serrated edges, lines of intersection ect are all know and used terms. I stand by my earlier comment because it is true and verifiable. A wing geometry is very important in designing an aircraft that can achieve low oberervability; serrated edges or whatever other term you prefer is there for a reason.
If my earlier post was too simplistic it is because none of you fanboys understand what Im talking about or even respect the laws of physics. But upon request I will make my post more credible.
Firstly, all wing designs give off edge diffraction, this usually occurs off of wing tips. The designers of 'stealth' aircraft such as B-2, pak-fa, F-22, ect incorporate those unusual serrated edges in order to minimize specular reflection or direct the diffraction away from the receivers.
Take a look:

And here is proof that sawthooth or serrated edges work for 'mitigating' or reducing edge diffraction:

It has been long know that wing sweep plays an important role in 'stealth' design. The wings themselves as well as the sweep of edges or tip of wings also reduce returns.
Again take a look:

This is another example as to why serrated edges are incorporated. It also is why the F-22 and pak-fa have those unusual wing-tips that are angled towards the rear of the aircraft. Most people fail to recognize the importance or relevance of a well designed wing, the goal is to transmit energy away from the receivers, this is achieved by many factors, but the most important and most widely used technique is serrated edges. Further, all stealth aircraft have smooth flat surfaces which is necessary because any protrusions can cause EM energy to diffract. But a smooth flat surface can actually cause EM energy to collect, something referred to as a 'traveling wave'. This is a delicate balancing act because although you want a smooth flat surface in order to have the smallest radar signature as possible, you also want to eliminate any imperfections as to not cause edge diffraction. Likewise, when a 'traveling wave' reaches its final destination (a wing or wing tip) it is absolutely essential that the wing is designed to re-direct or minimize EM energy, otherwise all that energy scatters of a poorly designed wing and makes it back to the receivers.

Let not play this game, it is the J-20 fanboys that are the aggressors. It is you and others like you that bring the pak-fa into every conversation, so why is it that whenever Chinese members start attacking the pak-fa they are innocent but when someone raises a good point about the J-20 or criticizes it they are trolls? The pattern is this, J-20 fanboy randomly spout nonsense about how the J-20 is 'more advanced' than the pak-fa and F-22 then when someone challenges that they are considered trolls. Another pattern is the utter nonsense that comes from J-20 fanboys, everything from single piece canopies to canards has been a humiliating disaster on their part, further none of the crap J-20 fanboys preach can be verified or proven. Even funnier is that the J-20 miraculously somehow defies physics. It is amusing how the pak-fa was 'not stealthy' because it had antennas and rivets but when some clearer photographs of the J-20 revealed the same those same J-20 fanboys never mentioned it again. Funny how some of the same things that the pak-fa was crucified for does not apply to the J-20. The definition of troll can be interpreted any different ways.
