Proper rcs testing will technically result into a fighter that seems rather analogous to the F-22.
So the ground tests for internal weapons bay have already happened? Nice!
Do you remember if it had saw-tooth edges?
No the edges were smooth as shown in this pic.
This is internal bay of J 20:-No the edges were smooth as shown in this pic.
it looked exactly similar to J20 weapon bay.

Scientists develop stealth tech

KOLKATA: India could soon be the third country in the world, after the US and France, to have a stealth bomber fighter aircraft in its armoury.
The Kolkata-based Indian Association for Cultivation of Science (IACS) has developed a technology to convert ordinary light combat aircraft into stealth jets that would go undetected on radar. The first stage of the experiment, which commenced in 1999, has been successfully concluded. The defence ministry has approved the technology and has given the go-ahead for "full-scale production" to begin. It is expected to start in about six months��� time.
According to IACS scientists associated with the project, the technology uses a special material to construct a shield on the plexi-glass canopies. It is the glass cover of the cockpit that usually betrays the presence of an aircraft as it reflects the laser beam that is emitted to catch them on the radar. The shield will cover the cockpit and deflect the laser beam on the shield in all directions.
"This will make sure the aircraft remains undetected on the radar. We are not sure if the same technology is used in France and the US. It has been developed in our own way and using our own techniques. If it works out well, this would be a big step for defence technology in India," said a scientist.
Defence officials said the advanced combat aircraft made in the US and France have a similar shield on the plexi-glass canopies. "This shield gives the canopies a golden tinge. This special layer scatters the laser beams
(I don't think he said laser beams
emitted from a radar site either on the ground or in the air (AWACS). We���ve been trying to develop this technology for some time. The shield developed by IACS will boost our indigenisation efforts," an official said.
During the exercises at Kalaikunda where US F-16s took part, IAF officials got a closer look at the gold-tinted canopies.They also got a chance to test the technique by using ground-based radar. Interestingly, the F-16s from Singapore did not have the shield as the technology has not been transferred.
The defence authorities were so impressed with the new technology that they decided to fast-track the process and start full-scale production of the canopy following a test at Jodhpur recently.
"They had the option of going for a pilot project initially but they chose to skip it," said an IACS official. Fighter jets like Jaguars, MiGs, Mirages and Sukhois will now be fitted with this special canopy to enhance their stealth capabilities.

Good slow and steady wins the race
RAM coating can be done with all the above, with the patented RAM.
With less 5g features, with that what he means, in terms of electronics or flight performance, I am sure they ain't gonna fly the aircraft without the FBO.
If i remember correctly, this stealth coating for the canopy was one of the reasons the Rafale deal collapsed. The French were unwilling to share this tech, and wanted HAL assembled Rafales to be taken to France for this coating. Apparently we wanted this tech very much. So this news does confuse me a lot. If we already had the tech, why would we push for it in a ToT agreement? Unless our coating was still not mass-producible.An old news article.

Looks like DRDO has managed to make a wide-band absorber based on this tech. The limitation of these kind of absorbers, apparently, was that they were not effective across multiple frequencies.
Found the paper:-
Dang that's a lot of useful information thanks may need it in the future
Look at the reference number 13 in the research paper in post number #3015. The Chinese do it too.
