One of the commonly used metal forming processes is deep drawing, in which circular blanks are converted into a cup or shell with good surface finish. In this paper, the forming characteristics of Deep Draw Steel (DDS), a low-carbon steel with many engineering and automotive applications, is investigated by deep drawing. The forming limit diagram is a(More)
TEM horn antennas are widely used in ultra wide band (UWB) radar and UWB communication applications due to its wide bandwidth and non-dispersive characteristic. Linearly tapered constant impedance TEM horn is most commonly used variation of TEM horn due to its simplicity and ease of fabrication. In many practical systems cylindrical sections are added at(More)
