21. A similar arrangement is used to suppress unwanted modes in metal-backed coplanar waveguide. 22. In 1960 Weimer began making thin-film transistors in a coplanar process on glass substrates. 23. The triangles of coordinating atoms and the central atom have two coplanar , and one perpendicular. 24. In many diagrams of the solar system, all of the planet's orbits are coplanar . 25. In this case, the forming vectors are non-coplanar , see Chen ( 1983 ). 26. On a smaller scale, coplanar waveguide transmission lines are also built into monolithic microwave integrated circuits. 27. Chemistry involving nickel catalysis of Suzuki reactions was greatly affected by pyrazoles and pyrazolates acting as coplanar ligand. 28. An easily prepared pincer ligand is POCOP . Many tridentate ligands types occupy three contiguous, coplanar coordination sites. 29. The rank of the above matrix might come out to be 4 even if practically the points are coplanar . 30. Transmission lines such as microstrip, coplanar waveguide, stripline or coax may also be considered to be waveguides.
