Hmmm ... Can anyone explain these shapes and structures ???? I need to admit I've never seen such things on a Western fighter.

There are similar structures on the f-22. On either side of the fuselage spine behind the cockpit.

MUCH, much better, Very nice.
Still waiting for the HD of the take-off, flight and landing though.
This is getting us much closer.
Those folks standing around watching remind me of the 60s and 70s in the US when new aircraft were tested and flown. Hundreds would stand and watch waiting for a glimpse. Lot's of good passion and pride in that.
They are likely some kind of passive antennae, to detect emissions, part of a grid to allow the aircraft to be quiet, and yet build a network of passive "awareness" of what is happening in the environment around the aircraft!
Also that light grey outline around the inlet is heating, the same on the canard which is likely constructed of carbon fiber, I suspect there is also lightning protection built into the carbon fiber as embedded filaments to carry the charge away and prevent lighting burn-through, the idea being to allow the lightning to pass through rather than burning its way through the aircraft and systems.
Those heated surfaces are necessary to prevent ice build-up and accumulations, I know what icing does to turbines, but I haven't read anything about icing and canards, but I assure you it would not be pretty! It wasn't until I was staring at those inlets that I thought about ice and that pretty paint around the edges of the canard. I must be slipping????
good post chuck... brat
good catch gullible, the ABs still have that blue flame on the burners!
I considered a Faraday's cage but cannot imagine why they would put one there and what they would put behind it that they couldn't do with a material transparent to the frequency.
I am not sure you can tailor the transparency of the material well enough. For example, if what lay behind the cage is a very short wave transmitter or receiver. I don't know any material that will be opaque to normal centimeter radar, but transparent to millimeter wave lengths or shorter.

But if it is a Faraday's cage it doesn't need to be exposed. It could have sat behind a cover that was transparent to the outbound and inbound frequencies (though I suppose they might not be able to find such a material as you've suggested). I'm also not sure they would design a sensor to be exposed like that, especially so close to the exhaust of a missile.

Like i said in another place, imo those meshes are simply air bleeds, but meshed over to make them LO to a certain radar band. PAK-FA seems to have similar meshes on each side of it's intakes. Think of F-117s intakes for instance (only in this case it's an air bleed not an intake; likely there is a movable flap behind each mesh)
