We propose in this work a general procedure to
efficient EM-based design of single-layer SIW interconnects,
including their transitions to microstrip lines. Our starting point
is developed by exploiting available empirical knowledge for
SIW. We propose an efficient SIW surrogate…

Studies on the impact of Eucalyptus spp. on Brazilian soils have focused on soil chemical properties and isolating interesting microbial organisms. Few studies have focused on microbial diversity and ecology in Brazil due to limited coverage of traditional cultivation and…
