Lower Bounds for Planar Arithmetic Circuits [PDF]

open access: yesACM Transactions on Computation Theory
Arithmetic circuits are a natural well-studied model for computing multivariate polynomials over a field. In this article, we study planar arithmetic circuits . These are circuits whose underlying graph is planar. In particular, we prove an Ω ( n

Silica-Based Planar Lightwave Circuits

open access: yesMRS Proceedings, 1999
AbstractSilica-based planar lightwave circuits (PLC) provide various important devices for both optical wavelength division multiplexing (WDM) networks and optical access networks. This paper is an overview of recent progress in PLC technology including optical power splitters, arrayed-waveguide gratings, thermo-optic switches, and hybrid integrated ...

Hamiltonian circuits in trivalent planar graphs.

open access: yes, 1973
The author has investigated the properties of Hamiltonian circuits in a class of trivalent planar graphs and he has attempted, with partial success, to establish conditions for the existence of Hamiltonian circuits in such graphs. Because the Hamiltonian

Efficient enhancements in spectral domain method to speed up open planar circuit analysis [PDF]

open access: yes, 1998
The spectral domain method is a very fast and powerful technique to analyse planar microwave circuits. Available techniques for simulating the excitation of open planar microwave circuits are not very effective at relatively low frequencies.

Planar gunn diode characterisation and resonators elements to realise oscillator circuits [PDF]

open access: yes, 2013
The paper describes the planar Gunn diode, which is well suited to providing milli-metric and tera hertz sources using microwave monolithic integrated circuit (MMIC) technologies. Different planar Gunn electrode geometries are described along with DC, RF

Induced Circuits in Planar Graphs

open access: yesJournal of Combinatorial Theory, Series B, 1994
Previously the authors have given a polynomial-time algorithm for the problem of finding a minimum cost circuit without chords (induced circuit) traversing two given vertices of a planar graph. The algorithm is based on the Ellipsoid Method. Here we give an \(O(n^ 2)\) combinatorial algorithm to determine whether two nodes in a planar graph lie on an ...

Optimized absorbing boundary conditions for the analysis of planar circuits using the finite difference time domain method [PDF]

open access: yes, 1993
It is shown that the description of absorbing boundary condition algorithms (ABCs) in terms of single incident plane waves does not provide sufficient information for choosing the best ABC for planar waveguide termination.

Design Technology Co-Optimization Strategy for Ge Fraction in SiGe Channel of SGOI FinFET

open access: yesNanomaterials, 2023
FinFET devices and Silicon-On-Insulator (SOI) devices are two mainstream technical routes after the planar MOSFET reached the limit for scaling. The SOI FinFET devices combine the benefits of FinFET and SOI devices, which can be further boosted by SiGe ...

Planar Beam Steerable Parasitic Array Antenna System Design Based on the Yagi-Uda Design Method

open access: yesInternational Journal of Antennas and Propagation, 2019
A planar beam steerable array antenna system is proposed with dual-control circuits for feeding and reactive loadings. Two orthogonally arranged planar dipoles are excited by SPDT switching circuits, while the forward and backward beam directions are ...
