    They've already made a experimental sample.

    The key detail I could discern from this text is that the illumination of the target is in a wide EM band instead of
    a narrow band like conventional radar. The wide band illumination results in more accuracy in position determination
    and photographic reconstruction of the illuminated object. This is a very plausible scenario since throwing
    many wavelengths at the target gives more information due to differential scattering, i.e. there is a new degree
    of freedom and hence information axis introduced.

    the key component is by using fiber optics , you dont need to put aperture in the nose like conventional radar , it is very thin so you can distribute it all over aircraft , nose , wings , verticals , tail , ... so during illumination it kinda gives synthetic aperture radar view of the object.

    With some serious computing power it could examine the radar return and the effect the target had on the return signal to determine all sorts of interesting new things...

    For instance the return of longer wave signals but the absorption or deflection of higher frequency signals will immediately identify a B-2 target for instance...

    Russian researchers have created an improved process to manufacture "transparent aluminum". Not quite the Star Trek BS, but close.
    Note that metals cannot be transparent by definition since they have mobile electrons and are thus strong absorbers in the whole EM spectrum.
    Oxides of metals can be transparent since they are insulators that lack mobile electrons. This particular glass is AlON (aluminum oxinitride) and
    has nice properties for use as bullet proof glass and in lasers.

    https://phys.org/news/2017-07-russian-scientists-technology-production-transparent.html

    Specialists from the National Research Nuclear University MEPhI and multi-institutional collaborators have developed a technology to produce compacts from aluminum oxynitride (ALON). They've published their results in IOP Conference Series: Materials Science and Engineering.

    To obtain "transparent aluminum," researchers at the Institute of nuclear physics and engineering (INPhE) MEPhI applied the method of spark-plasma sintering. This is a new sintering process based on the modified method of hot pressing. In this case, electric current is passed directly through the mold and pressing billet, but not through an external heater. Very rapid heating is achieved by pulsed current for an extremely short work-cycle time.

    "Among all present ceramics of medium density, aluminum oxynitride has a significantly high strength, comparable to that of YAG ((yttrium aluminum garnet) and cubic zirconia (stabilized zirconium oxide). Its toughness, which is the most important characteristic for armor protection, surpasses those of all transparent materials including quartz glass, fused quartz, spinel and leucosapphire," explains one of the authors of the publication, postgraduate student of INPhE Nikita Rubinkovskii.

    Fans of Star Trek will recall that in the fourth movie, The Voyage Home, a material called "transparent aluminum" plays an important role in the story. Such materials have already been created and successfully used. It's four times stronger than aluminosilicate glass, and more scratch resistant. In addition, this material can withstand temperatures up to 2100 degree Celsius.

    Currently, the penetrating power of small arms and small-caliber artillery forces the developers of protection equipment to improve the performance of armor materials and protective structures. This is especially true of transparent armor materials. Transparent polycrystalline ceramics is the most promising in this respect, in particular, ceramics based on aluminum oxynitride. It is possible to obtain transparent products of complex shape using the ceramics technology processes of molding and sintering.

    The developers also claim that ALON can be used in several military and commercial applications, e.g., windows and domes for spacecraft and outer transparent armor.
