Thermal\ transport\ across nanosized constrictions is calculated considering wave effects. It is shown that Rayleigh-type\ phonon\ diffraction reduces thermal\ transport\ across nanosized constrictions at low temperatures. We show that for\ $\ \ a\ \ T\ \ \&$\#$x2215;\ \ \ v\ \ Debye\ \ \ \<\ \ 0.01\ \ \&$\#$xD7;\ \ \ 10\ \ \ \&$\#$x2212;\ \ 9\ \ \ \$ , where\ $\ a\ \$ \ is the radius of the constriction,\ $\ T\ \$ \ the temperature, and\ $\ \ v\ \ Debye\ \ \$ \ the Debye velocity of the solid material, diffraction effects are important.
