Could you tell me how to see co &cross polarization for dual polarizated square MSA in hfss v11 for e-plane & h-plane?

how to decide from s/w design it is linear or circular polarization?


Thanking you in anticipation.

Matrix Treatment of Polarization


Polarization

Polarization of an electromagnetic wave is direction of the electric field vector E.
Mathematical presentation of polarized light: Jones Vectors


Usefulness and some properties of the Jones vectors
Two properties of the polarization vector or Jones vector :

1) polarization state of a wave does not change if its Jones vector is multiplied by a constant.
It only affects the amplitude.

2) polarizatio

This innovative technology can produce smaller, faster and efficient cryptographic keys using the break through technique of elliptic curve equation rather than employing the traditional method of producing the key as the product of very large prime numbers. Although ECC can be used in collaboration with other public key encryption methods like the RSA, and Diffie-Hellman, it gains upper hand over the other encryption methods in the level of security it offers. A 164-bit ECC key can provide with an equivalent amount of security that a 1024-bit ....etc

ABSTRACT

The main objective of our Project is to show that Elliptical Curve Cryptography is better than RSA. Which means than the ECC maintains a constant key size regarding the amount of data transferred i.e. the key size will be constant where as in RSA key size varies with increase in transfer of data. By having this type of properties this algorithm can be used in different applications efficiently. This algorithm is widely applicable to the huge organizations like military. As in the military network large amounts of very ....etc

Abstract—


A geometric relationship and mathematical model of pressure angle of elliptical gears are developed based on the theory of gearing, and some constraints of pressure angle are presented in order to prevent gear teeth from coming out of mesh. The results show that the ....etc

ECC is a public key encryption technique based on elliptic curve theory. ECC can be used to create faster, smaller and more efficient cryptographic keys. It generates keys through the properties of the elliptic curve equation rather than the traditional method of generation, as the product of very large prime numbers. This technology can be used in conjunction with most of the public key encryption methods such as RSA and Diffie-Hellman. ECC can yield a level of security with a 164-bit key compared with other systems that require a 1,024-bit ke ....etc
