This paper proposes a three-dimensional (3D) communication channel model foran indoor environment considering the effect of the Hypersurface. TheHypersurface is a software controlled intelligent metasurface, which can beused to manipulate electromagnetic waves, as for example for non-specularreflection and full absorption. Thus it can control the impinging rays from atransmitter towards a receiver location in both LOS and NLOS paths, e.g. tocombat distance and improve wireless connectivity. We focus on the 60 GHzmmWave frequency band due to its increasing significance in 5G/6G networks andevaluate the effect of Hypersurface in an indoor environment in terms ofattenuation coefficients related to the Hypersurface reflection and absorptionfunctionalities, using CST simulation, a 3D electromagnetic simulator of highfrequency components. To highlight the benefits of Hypersurface coated wallsversus plain walls, we use the derived Hypersurface 3D channel model and acustom 3D ray-tracing simulator for plain walls considering a typical indoorscenario for different Tx-Rx location and separation distances.
