1. Wide Band Stop Response Using Interdigital Capacitor/CSRR DGS in Elliptical Microstrip Low-Pass Filter
Abstract In this paper, a compact elliptic-response microstrip low pass filter (LPF) is presented with a wide stop-band using stepped impedance resonators. With high attenuation in the stop-band, the overall size reduction of the proposed filter is achieved using a novel defected ground structure technique using an interdigital capacitor and complementary sp

2. Sharp Rejection and Wide Stopband Microstrip Lowpass Filters using Complementary Split Ring Resonators
Abstract Chebyshev microstrip lowpass filters with improved performance, achieved by means of circular complementary split ring resonators (CSRR), are presented. CSRR particles exhibit frequency rejection bandwidths in the vicinity of their resonant frequencies that can be used to meliorate both selectivity and stopband in microstrip lowpass filters. Two con

3. Experimental Study of Transmission and Reflection Characteristics of a Gradient Array of Metamaterial Split-Ring Resonators
Abstract A study of a non-uniform metamaterial array consisting of six split-ring resonators of varying diameters is conducted experimentally to measure the transmission and reflection characteristics that arise from asymmetry in the longitudinal direction. Such characteristics are examined and compared with their counterpart symmetric scattering coefficient

4. Effect of Complementary Split Ring Resonator Structure on PIFA Antenna
Abstract This paper proposes a new design of Planar Inverted-F Antenna with complementary split ring resonators (CSRRs). The operating frequency of this antenna is 2.425 GHz for Wireless Local Area Network (WLAN) application. The method is to incorporate a single CSRR cell and a periodic array CSRRs on the radiating patch. We studied the effect of this metho

5. Metamaterial inspired improved antennas and circuits
Metamaterials exhibiting negative refraction have attracted a great amount of attention in recent years mostly due to their exquisite electromagnetic properties. These materials are artificial structures that exhibit characteristics not found in nature. It is possible to obtain a metamaterial by combining artificial structures periodically. We investigated t

6. Modeling of nano-structures for applications in generation - Plasmon Surface Polariton (SPP) / Modelagem de nano-estruturas para aplicações na geração de Plásmon-Poláritons de Superfície (SPP)
O incessante aumento do volume de informações produzido por uma sociedade cada vez mais informatizada tem elevado drasticamente os requisitos quanto ao desenvolvimento de dispositivos capazes de suportar velocidades de operação cada vez mais elevadas em tamanhos cada vez mais reduzidos. No entanto, a contínua redução do tamanho desses dispositivos, ce

7. Modeling of Dual-More resonators with the aid of the FDTD method for project of microwave filters / Modelamento de ressoadores dual-mode com o auxílio do método FDTD para projeto de filtros de microondas
The increasing demand for telecommunications services and the congestion of the radio frequencies spectrum have motivated the development of new devices with performance improved and small dimensions. This work will focus on dual-mode ring resonators and its applicability on the issue of assembly of filters. Initially, the model of the ring resonator and its
