As the appliance of the integration process of the Yangtze River Delta and the Shanghai Combined Ports strategy, Nantong, which locates in the Jiangsu riverbank development zone and in the eastern oceanic Jiangsu construction areas, is paid great attention to because of its special location advantage. Thus how to make good use of the outstanding port and coast resources to develop the advantage...

The authors have introduced stochastic port-Hamiltonian systems and have clarified some of their properties. Stochastic port-Hamiltonian systems are extension of deterministic port-Hamiltonian systems, which are used to express various deterministic passive systems. However, since only time-invariant case has been considered in our previous results, the aim of this paper is to extend them to ti...

A novel omnidirectional circularly polarized (CP) slot array antenna with high gain is proposed, which is based on the coaxial cylinder structure, and the orthogonal slots radi‐ ated the circular polarization wave around the cylinder. Further, the improved dual cir‐ cularly polarized (CP) omnidirectional antenna based on slot array in coaxial cylinder structure is presented too, and two ports a...

This paper presents an infinite impulse response (IIR) structure for designing a three-port optical interleaver. With the proposed IIR structure, the spectral responses of the interleaver can be designed in two steps to achieve simultaneously three channels of identical but 2pi/3 shifted passband transmissions. Compared with a three-port finite impulse response (FIR) interleaver, the proposed I...

A port controlled Hamiltonian formulation of the dynamics of distributed parameter systems is presented, which incorporates the energy flow through the boundary of the domain of the system, and which allows to represent the system as a boundary control Hamiltonian system. This port controlled Hamiltonian system is defined with respect to a Dirac structure associated with the exterior derivative...

A W-band dual-polarized Cassegrain antenna for cloud radar is proposed. The aperture diameter of the main reflector of the antenna is 50 cm. By using a modified Magic-T structure in the feed horn, the antenna is dual-polarized with high port isolation. The measured results show that the port isolation is 44.7 dB. The gains are 47.3 dB and 49.5 dB for the two ports at 94GHz, respectively, and th...

We present the mixed Galerkin discretization of distributed parameter port-Hamiltonian systems. On the prototypical example of hyperbolic systems of two conservation laws in arbitrary spatial dimension, we derive the main contributions: (i) A weak formulation of the underlying geometric (Stokes-Dirac) structure with a segmented boundary according to the causality of the boundary ports. (ii) The...
