“…[ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. Even though a large number of dielectrics with suitable properties have been reported [ 10 , 11 , 12 , 13 , 14 , 15 ], their mass production is restricted due to the manufacturing costs and technological limitations. As a consequence, ceramic materials became the most employed in passive MW devices due to the simplicity, cost effectiveness, and scalability of their large-scale fabrication.…”
