As stated, this is not a new idea. Unlike constant power tapering, the absorption tapering is frequency dependent, which is an added degree of freedom to facilitate a better design.
I use a similar principle in my waveguides to improve pattern control - a foam plug - and it works extremely well. It is an idea with a lot of potential, but it can be very difficult to actually design using.
