You need to stop believing that crap from Rachel Maddow. The F-22 has far less absorber than the F-117 does. The reason why extra care must be taken in maintenance is not because of the material itself but because of minute surface imperfections that may raise the aircraft's RCS above a certain threshold...
But for now, low radar observability is the highest. The F-22 may be costly, but losing a war or publicly capitulate because your air force has been shredded is much more expensive. Your choice.
You need to stop believing that 'continuous curvature' crap. That phrasing does not exist in low radar observable engineering literature. At least not in the reputable kind.
Speaking for myself: Ten years active USAF and almost ten more years in civilian aviation in the same avionics field. I used to design field tests involving radars and targets, air- and water-borne, off the Florida coast.
Not for RCS maintenance but for panels that are designed for maintenance purposes. Those panels have gaps that will raise certain areas above a certain threshold and those gaps cannot be helped IF the aircraft is to be field maintainable. So the 'zip strips' are used to cover up those gaps.
Give me a credible source for that 'continuous curvature' phrasing. I want to see its proper context.I Guess Even F-22 uses a combination of different ways (including Continuous curves ) to keep radar waves from bouncing back to their origin ?

The idea behind that phrasing is 'surface discontinuities' and it is a more accurate and precise descriptor on how these post F-117 aircrafts are designed. Surface discontinuities can be large or small and even structural, as where two or more structures meet and because of aerodynamic demands, a curvature must be interrupted. The one thing I consistently try to do here is introduce the correct terminologies used in the field.Gambit Google is Not My friend
That the best i can try for now

Yes. Try to differentiate between material formula versus structure. Ferrite particles embedded below the surface is material. Gouges, nicks, and dings from flight or rocks stuck on underside of boots are structural, meaning they do not affect the ferrite particles at all. A gouge is a structural defect.
They are called 'booties'. Once I was assigned to work on a 'special' F-16 that required 'booties' to go over the combat boots. Either that or remove the combat boots completely prior to climbing on the aircraft. Other guys did not know why this F-16 was 'special' but I did. People have no idea how much the F-16 was the test bed for so many 'stealth' principles that became applications. The F-16 will have a very honored place in aviation history in more ways than believe.
For the F-22, absorbers are strategically placed at leading edges such as flight control surfaces and intake lips. Much are said about composites relating to 'stealth' but the truth is that composites on the F-22 and F-35 are more for weight saving measures than for RCS control. Composites does not automatically equal to 'stealth'. Concrete and plywood are composites -- gross. Stainless steel is a composite -- molecular. When shaping is enough to lower RCS to below a certain level, absorber that will increase maintenance complexity and manufacturing costs while are of negligible benefits is no benefit at all.
