今天，電路理論的學科已經超越了傳統的界限，而電路理論思想的應用在許多不同的科學和工程領域做出了顯著的貢獻。國際電路理論與應用雜志致力于出版有關理論及其應用的原著。出版材料的本質特征是，電路理論的思想或技術應該在解決或闡明問題中起到突出的作用。將描述電路理論和電路理論概念應用進展的論文匯集在一起，既有助于促進這些概念的廣泛應用，也有助于對電路理論學家提出新的挑戰。主持該期刊的編委會來自許多國家，目的是盡可能廣泛地與主題領域保持聯系。麻管局在將文件轉介至最高國際標準方面也發揮著重要作用。該雜志的范圍包括模擬電路和數字電路的理論和設計的各個方面，以及電路理論的思想和技術在其他科學和工程領域的應用。所涉及領域的示例包括：基本電路理論及其數學和計算方面；設備的電路建模；濾波器和有源電路的合成和設計；神經網絡；非線性和混沌電路；信號處理與超大規模集成電路；分布式、開關和數字電路；電力電子；固態設備。歡迎為計算機輔助設計和仿真做出貢獻。稿件可以是給編輯的論文或信件。論文（每篇限制在7500字以內）可以是研究性的或指導性的，出版要求可以簡單地表述為原創性和意義。給編輯的信（每封限制在2500字左右）也必須是原創的，但通常包含對某個主題的更為有限的報道，或者呈現一些初步結果。給編輯的一封信也可以對發表的結果發表評論，提出一些新的問題，引起對某些應用的關注，或者是對技術感興趣的。期刊的特刊不時出版。這些都是專門討論一些當前重要的話題，并由受邀的客座編輯編輯編輯。這類特殊問題是通過在雜志上征文來宣布的，客座編輯負責選擇要發表的論文。

Today, the discipline of Circuit Theory has extended far beyond its traditional boundaries, while the application of circuit theoretic ideas has made notable contributions to many diverse fields of science and engineering. The International Journal of Circuit Theory and Applications is devoted to the publication of original work on both the theory and its applications. The essential feature of the material published is that the ideas or techniques of Circuit Theory should have played a prominent part in the solution or elucidation of the problem. The bringing together of papers describing advances in the theory and in the application of circuit theoretic concepts is intended to be of interest both in stimulating the wider use of such concepts and in posing new challenges for the circuit theorist.The Editorial Board which presides over the Journal is drawn from many countries in order to maintain contact with the subject area on the widest possible basis. The Board also plays an essential part in the refereeing of papers to the highest international standards.The scope of the Journal comprises all aspects of the theory and design of analog and digital circuits together with the application of the ideas and techniques of circuit theory in other fields of science and engineering. Examples of the areas covered include: Fundamental Circuit Theory together with its mathematical and computational aspects; Circuit modeling of devices; Synthesis and design of filters and active circuits; Neural networks; Nonlinear and chaotic circuits; Signal processing and VLSI; Distributed, switched and digital circuits; Power electronics; Solid state devices. Contributions to CAD and simulation are welcome.Contributions may consist of Papers or Letters to the Editor. Papers (each limited to about 7500 words) may be of a research or tutorial nature and the requirements for publication may be briefly stated as originality and significance. Letters to the Editor (each limited to about 2500 words) must also be original but generally comprise a more restricted coverage of a topic, or present some preliminary results. A Letter to the Editor may also comment on published results; pose some new problem; draw attention to some application or otherwise be of technical interest. From time-to-time Special Issues of the Journal are published. These are devoted to some topic of current importance and are edited by invited Guest Editors. Such Special Issues are announced through a Call-for-Papers in the Journal and the Guest Editors are responsible for the selection of papers to be published.
