Substrate integrated waveguide (SIW) is a technique to implement waveguide into microstrip material that can be applied to filter, antenna, mixer, coupler, and so on. Implementation of SIW to filter can overcome the problem of size reduction and high... see more

The effect of source, geometrical and physical parameters of slab waveguide on the sensitivity of optical sensor and its evanescent field have been investigated. The waveguiding film of LiNbO3 was fabricated and the observations revealed that the maximal ... see more

The problem of electromagnetic wave pressure on a thin conductive vibrator located in a rectangular waveguide is solved. Wave H10 falls on the vibrator. The vibrator is located perpendicular to the wide wall of the waveguide. The current in the vibrator a... see more

The paper deals with numerical solution of Maxwell equations by the method of finite differences in the time domain for bodies of revolution (BOR-FDTD) in an open domain using moving frame. The latter made possible to calculate long time propagation of a ... see more

The excitation of wake waves by the electron bunch in an isotropic plasma-dielectric waveguide is studied. It is shown that the excited field consists of two components: the field of the Langmuir wave and the field of eigenmodes of a dielectric waveguide.... see more

A LabVIEW based general purpose module to understand and visualize the electromagnetic field patterns inside the commonly used microwave devices is developed. The module provides both the electric and magnetic field patterns for any arbitrary mode config... see more

We study the coupling and switching effects of two discrete relativistic quantum Jackiw-Rebbi states in interfaced binary waveguide arrays with cubic-quintic nonlinearity. Like in the case with Kerr nonlinearity, two Jackiw-Rebbi states can couple efficie... 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
