    Abstract: An inspection apparatus inspects a pressure vessel using laser ultrasound. The apparatus includes an oscillation device that oscillates an excitation laser for exciting the pressure vessel and a conduit to guide the excitation laser oscillated from the oscillation device to inside the pressure vessel. The conduit is inserted into the pressure vessel with one conduit end located inside the pressure vessel and an opposite end located outside the pressure vessel. The apparatus includes a reflector at one conduit end inside the pressure vessel to reflect the excitation laser guided by the conduit and a detector that detects ultrasonic waves generated in the pressure vessel by the excitation laser reflected by the reflector by oscillating a receiving laser from outside of the pressure vessel. At least the conduit, reflector, or detector moves to correct an optical path of the excitation laser or the receiving laser.

    Abstract: A stealth antenna includes an electromagnetic wave absorbing structure and an antenna patch embedded in the electromagnetic wave absorbing structure. The electromagnetic wave absorbing structure includes an upper dielectric layer, a lower dielectric layer and a spacer disposed between the upper dielectric layer and the lower dielectric layer. The upper dielectric layer includes a dielectric fabric and a conductive coating layer combined with at least a portion of the dielectric fabric. The lower dielectric layer includes a dielectric fabric and has a dielectric constant lower than that of the upper dielectric layer. The antenna patch is disposed between the spacer and the lower dielectric layer.
