In last decade, many of researches have proposed to study materials with periodic
structures,These structures can be engineered to realize novel electromagnetic properties
and to achieve behaviors that are not found in naturally materials. These ma
terials have
negative permittivity and permeability .Those are called meta-material or Left Hand
Material (LHM), They are fabricated, studied and analyzed within different applications of
microwave and optical communication. Recently, the microwave engineering applications
of artificial metamaterials have been widely discussed and various novel microwave
components were achevid for example, filters, antennas and fiber optic. This paper studys
and analyzes the reflection from fractal distribution of MMs layers in RHM medium, using
the recursive method, and applies it in the design of microwave narrow band filters.
Research over the past years has focused on electromagnetic waves and meta-materials. These structures are designed to give electromagnetic properties that cannot be produced by traditional, well known natural structures. Meta-materials obtain their
electromagnetic properties from their structures, not from their components. Meta-materials have new properties that define different mechanisms for electromagnetic wave propagation. These materials have been studied theoretically and have been used in many applications, especially microwaves and photonic fields. This research depends on these kinds of material, explains them, and analyzes the electromagnetic properties that yield from putting columns from these slabs with negative permittivity and permeability coefficient (MMs) in a fractal distribution of a natural medium. This research also compares the resulting properties with the electromagnetic properties that yield natural materials distributed the same way. We use the HFSS simulator which depends on the finite element method for calculating transmission and reflection coefficient for these structures.
.In this paper we present a new method to improve microstrip
patch antenna bandwidth to support 5Generatiton and previous
generations frequency bands ,at our proposed method multi slots
have been made in microstrip patch antenna to get the
maximu
m current distribution on the surface & get desired
improvements.
Recently PGB (photonic band gap) filters show a great
development. Here we will present two different PGB filters with
lattice etched in the ground plane. The rejection band characteristic
is function of the number and shape of elements etched. Th
ese
filters are modelling by the FWCIP method.
In this paper we will study the usage of equivalent circuit; in
modeling a round shaped metal cylinder in rectangular waveguide
to get filters that can be calibrated and used in the microwave
domain. We will study the structure of a rectangular re
sonant
cavity linked stimulatory through thick openings. Also a metal
shape to be calibrated in rectangular resonant cavity linked
stimulatory through thick openings. We will use matlab for showing
transition and reflection factors for the suggested filters.
