Hi everyone,
I need to trace the simulated transfer function of an UWB antenna as well as the normalised signal strength to compared it with the measured one. Any help? using CST or HFSS software!
What is the main difference between SCI- and ISI-indexed journals? JCR (stands for Journal Citation Reports) is also produced by Thomson Reuter, are they the same thing?
