Characterization and synthesis of self-complementary normal bases in finite fields

Abraham Lempel
1988 Linear Algebra and its Applications  
A finite extension Q, = GF( 9") of a finite field F = GF( 9) has a self-complementary normal basis over F iff either n is odd or n = 2 (mod 4) and 9 is even.  ...  This paper presents a complete characterization of square matrices A of order n over F such that the set { A9'):;; is a self-complementary normal basis of a matrix representation of Cp over F.  ...  In this paper we deal with bases of Q, over F which are both self-complementary and normal (for short, SCN bases).  ...

Characterization of self-complementary symmetric digraphs

Hong Zhang
1996 Discrete Mathematics  
The class of self-complementary symmetric digraphs is characterized and it is shown that the number of vertices of such a digraph is an odd prime power. Let G be a group and H be a subset of G.  ...  Construction A family of self-complementary symmetric digraphs can be constructed based on finite fields. The construction is similar to those in [2, 4] .  ...  Let p be a prime and F the finite field with p" elements.  ...

Energy loss of terahertz electromagnetic waves by nano-sized connections in near-self-complementary metallic checkerboard patterns

2017 Journal of Applied Physics  
We show that finite conductivity and randomness in a near-self-complementary checkerboard pattern plays a crucial role in producing a frequency-independent energy loss in the terahertz frequency region  ...  When the checkerboard pattern approaches the perfect self-complementary pattern, the perfect conductor approximation spontaneously breaks down, owing to the finite conductivity at the nano- scale connection  ...  At the limit of a perfect self-complementary checkerboard pattern in a realistic system, the finite conductivity and randomness in the structure needs to be considered.  ...
