Following Eringen’s theory, the question whether a Stoneley mode can exist at an unbonded interface between two micropolar elastic half-spaces is examined analytically. Explicit conditions for its existence are derived when the two half-spaces are incompressible or Poisson solids whose material properties are close to each other.
