Ultrasonic technology has already been used for many applications. Most of them are mainly used for object measurement. Some techniques have been widely applied to particular measurement by utilizing a very specific component. In this research, the previo... see more

The layered media under one-dimensional strain with different wave-impedance materials have been studied. The three typical prototypes have been analysized, including steel plate, aluminum foam, and concrete as the middle layer, and the upper and lower la... see more

On the basis of the projection method the rigorous solution of the basic wave ?10 diffraction problem on a joint of a regular and non-regular waveguides with a dielectric plate placed parallel to narrow impedance walls is presented. The problem is solved ... see more

Rigorous solution of the principal H10 wave diffraction problem at the joint of regular and non-regular (narrow walls are formed by secondary waveguides) rectangular waveguides has been obtained using the method of projection matching. On the basis of num... see more

In transportation engineering, there is the need of having quick and reliable tools for estimating the acoustic power radiated by a given elastic surfaces. Normally, the computational and experimental tools, or their combination, are based on CPU time-con... see more

Electromagnetic (EM) wave has become an integral part of this electronics dominated era with extensive application in wireless communication, health care, and military applications. This has led to the development of EM wave absorbers for camouflaging the... see more

In this study, a wideband circularly polarised (CP) antenna is developed and demonstrated. The antenna comprises of two-layered substrates, the top layer holds a driven patch and eight surrounding parasitic patches of similar dimensions, and substrate int... see more

In this study, a planar cavity-backed bow-tie-complementary-ring-slot antenna is proposed, and a new approach for bandwidth enhancement using a shorted-via is introduced. A shorted-via concept overcomes the narrow impedance bandwidth of a conventional sub... see more

The technique of feeding a microstrip antenna with a microstrip line through an aperture is gathering a lot of interest in communication and radar systems used for defence applications.This is due to the fact that this feeding technique has many adjustabl... see more
