characteristics of electromagnetic waves in a dielectric slab waveguide with a periodic slot …

Tunable-filter operation of an optoelectronically generated periodic microwave structure in a
semiconductor-based CPW can be achieved by means of a CW-illuminated slot array mask …

A physical optics approach has been found to be very fruitful in designing antennas that
make use of the diffraction phenomenon. Flexibility in forming a desired wavefront is …

Silicon nitride is a subject of growing interest with the potential of delivering planar
integrated optical devices as a complementary part of silicon photonics. The material has a …

The thesis explores different compact planar antenna structures and their applicability in the
field of microwave engineering. The overall contribution can be divided into three parts. In …

This paper theoretically presents TM electromagnetic plane wave scattering characteristics
of an optically controlled subwavelength slot grating with an electrically small period on a …

Terahertz radiation is a regime of the electromagnetic spectrum located in the far-infrared
just between the infrared and microwave. The terahertz range typically comprise frequencies …

A TM mode analysis in a metamaterial based dielectric waveguide is proposed and
introduced. Rigorously derived from Maxwell's equations, the dispersion properties are …

Electromagnetic metamaterials (MTMs) with simultaneous negative permittivity and
permeability, or left-handed materials (LHMs) are a very interesting and eye opening …
