In this letter, a novel coding metasurface (CM) based on low Q resonators and fast
optimization method is proposed to achieve wideband radar cross section (RCS) reduction …

An intimate relation is established between non-Foster reactive elements and loss-
compensated negative-group-delay (NGD) networks. It is shown that any possible network …

We will demonstrate an alternative topology for the feedforward amplifier. This amplifier
does not use a delay element, thus providing an efficiency enhancement and a size …

This paper deals with the similitude between the behaviours of linear filter gain and negative
group delay (NGD) function. The transposition method of low‐pass/high‐pass, low …

A comprehensive method to synthesize negative group delay (NGD) in the microwave
regime with a maximally flat response is proposed in this paper. This method is based on …

A fundamental theory of coupled line coupler-based negative group delay (NGD) topology is
established in this paper. The microwave circuit under study consists of the isolated-and …

In this paper the asymptotic limits of negative group delay (NGD) phenomena in multi-stage
RLC resonator-based circuits are discussed. A NGD-bandwidth-product limit is derived as a …

This paper presents a novel approach to the design and implementation of a distributed
transmission line negative group delay filter (NGDF) with a predefined negative group delay …

An innovative theory on the passive circuits capable to generate low‐pass negative group
delay (NGD) behaviour is introduced. An identification method enabling to identify the first …

A novel circuit is presented for the design of transmission‐type negative group delay circuit
(NGDC) with low signal attenuation. By loading a lumped resistor at a specific point on the …
