in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...

The multi band microstrip antenna is realized either by placing stub on the edges of the patch or by cutting slots at an appropriate position inside the patch or by using the combination of these two methods. In this paper an analysis to study the effects of stub and slot in dual stub loaded and stub loaded pair of rectangular slot cut rectangular microstrip antennas is presented. The additiona...

Recently, several designs of single fed circularly polarized microstrip antennas have been studied. Relatively, a few designs for achieving circular polarization using triangular microstrip antenna are available. Typically existing design of single fed circularly polarized triangular microstrip antennas include the use of equilateral triangular patch with a slit or a horizontal slot on the patc...

This paper demonstrates a power supply noise reduction using on-board stubs. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply noise of the designed frequency. Preliminary experiments show that 87% of the designed frequency noise component is suppressed when stub patterns are written on a power supply area on...

This paper compares a stub and a decoupling capacitor for power supply noise reduction. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply bounce of the designed frequency. The conditions where the stub is more effective than the same-area decoupling capacitor are clarified. The stub will work more efficiently...

base types in any byte order. USC requires stub parameters that give the lengths of any variable length array arguments. The code below copies one variable length character array to another. len gives the current length of the arrays. void foo (len, str1, str2) int len; /* Must be a native type */ char str1[len]; /* May be native or not */ char str2(1, 4, 4, <0>)[len];/* May be native or not */...

In this paper we propose a self-addressing framework for mobile ad hoc networks (MANETs) based on the degenerated use of network address translation (NAT) where each node builds its private “address map”. In contrast to previous proposals, MANET nodes do not need to coordinate in order to generate unique (IP) addresses. This solves an important autoconfiguration problem for MANETs and fits well...

A novel circular micro strip dual band stub loaded antenna is described. The antenna is built with a dielectric constant of (?r =2. 33) with RT/5870 as the substrate material. Due to the effect of stub loading, dual frequency is produced at 1. 88 GHz and 2. 73 GHz respectively for the stub length=17 m. m. With the further increment of stub length, shifting of secondary resonant frequency is pos...

A supercondensed TLM node for modelling inhomogeneous anisotropic media on an arbitrarily graded mesh without using stubs is developed. It requires less storage, computationally is more efficient and can operate on a higher time step then existing TLM nodes. Complete derivation, implementation and validation of the new node are presented in the paper. Introduction Transmission-Line Modelling (T...

The use of a stub code generator can greatly reduce the effort required to implement a multi-server system on top of a microkernel. However, stub code has traditionally been highly generic and therefore rather slow, which has prevented it from being used in performance-critical applications. In this work, we show that this restriction can be eliminated by specialization for the underlying platf...
