A chalcone single crystal, 1-(4-chlorophenyl)-3-(4-methoxyphenyl)prop-2-en-1-one that is transparent over the visible to infrared region is introduced as a new potential material to third-order nonlinear optical applications. The crystal exhibits ult

We consider the propagation of p-polarized electromagnetic waves obliquely incident on stratified random dielectric media. Using the invariant imbedding method generalized to random media and applying the random phase approximation, we derive a simpl

We study the characteristics of microstrip ring exhibiting photonic band gap properties. Since the stop band is caused by the reflection of electromagnetic waves at the narrow gap introduced in the ring, the geometry of the ring can influence on the

This paper presents a compact microstrip low-pass filter with ultra-wide stopband and sharp cutoff frequency response. The conventional shunt open-stub filter with a slot on the ground plane has a wide stopband at high frequency, and the coupled open

We study the control of the anisotropic optical properties of the two-dimensional (2D) dielectric photonic crystals (PCs) in a long-wavelength limit. It is achieved either by distorting the symmetry of 2D PCs or by changing the dielectric constant of

We have investigated optical transmission due to resonant tunnelling through metal/dielectric multilayers using the tight binding model and the invariant embedding method. The tight binding model for the resonant modes in metal/dielectric multilayers

The nucleation of copper (Cu) with (hfac)Cu(VTMS) organometallic precursor is investigated for Si, SiO 2 , TiN, and W 2 N substrates. As the deposition temperature is increased, the dominant growth mechanism is observed to change from the nucleation

We proposed a new lateral double-diffused MOS (LDMOS) structure employing a double p/n epitaxial layer, which is formed on p− substrates. Trenched gate and drain are also employed to obtain uniform and high drift current density. The breakdown volt

The application of photonic band gap (PBG) structures to a microwave switch is studied. For this purpose, a frequency selective multiplexer is implemented combining one-dimensional PBG structures. The tunability of microwave photonic crystals (PCs) w

It is generally believed that the spatial periodic variation of a dielectric constant $\ensuremath{\epsilon}$ or refractive index $\sqrt{\ensuremath{\mu}\ensuremath{\epsilon}}$ can give rise to photonic band gaps. However, through microwave experimen
