TRAVELING WAVE SPOT PROBE

摘要

Various examples of methods and systems are provided for traveling wave spot probes. In one embodiment, among others, a traveling wave spot probe includes one or more antennas positioned proximate to a coated surface. The one or more antennas can be configured to excite a surface traveling wave moving over an area under test by launching radio frequency (RF) energy at approximately a grazing angle to the coated surface under test. The one or more antennas can be positioned on a base placed proximate to the coated surface. The base can define the area of the coated surface under test. In another embodiment, a method for non-destructive testing of a coated surface includes positioning one or more antennas proximate to a coated surface and exciting a surface traveling wave over an area under test by transmitting RF energy via at least a portion of the one or more antennas.

主权项

1. A traveling wave spot probe, comprising:
a base placed proximate to a coated surface, the base defining an area of the coated surface under test; and one or more antennas positioned on the base, the one or more antennas configured to excite a surface traveling wave moving over the area of the coated surface under test by launching radio frequency (RF) energy at approximately a grazing angle to the coated surface under test.
