  • Patent number: 11933726
    Abstract: A measurement apparatus includes a generator that causes electromagnetic waves to be incident on a sample, a receiver that receives electromagnetic waves reflected by the sample, and a controller that controls the generator and receiver. The sample includes a first layer on which the electromagnetic waves are incident and a second layer stacked on the first layer. The controller detects whether a third layer is present between the first and second layers based on the electromagnetic waves incident on the sample from the generator and the electromagnetic waves received by the receiver. The generator causes the electromagnetic waves to be incident at an angle such that the electromagnetic waves are totally reflected between the first and third layers and/or between the first and second layers.
