A composite material with a ballistic protective effect having a first, outer layer made of a first steel alloy and at least one second layer which is arranged under the first layer and is made of a second steel alloy. The method includes dealing the first hand of cards and the second hand of cards. The first portion of the via-hole conductor structure has a truncated-cone shape tapering toward the conductor portion. Similarly, each transmit path upconverts a baseband signal to be transmitted by an assigned antenna. dRE2O3, wherein M is at least one of Na, K and Li, M\u2032 is at least one of Y, Gd, La, Sc and Lu, RE is at least one of Ce, Tm, Tb, Ho, Dy, Er, Nd, Sm, Eu and Pr.
